RESUMO

BACKGROUND: The rising prevalence of electronic cigarette (e-cigarette) and hookah use among youth raises questions about medical trainees' views of these products. We aimed to investigate medical trainees' knowledge and attitudes toward e-cigarette and hookah use. METHODS: We used data from a large cross-sectional survey of medical trainees in Brazil, the United States, and India. We investigated demographic and mental health aspects, history of e-cigarettes and tobacco use, knowledge and attitudes toward e-cigarettes and hookah, and sources of information on e-cigarettes and hookah. Although all medical trainees were eligible for the original study, only senior students and physicians-in-training were included in the present analysis. RESULTS: Of 2,036 senior students and physicians-in-training, 27.4% believed e-cigarette use to be less harmful than tobacco smoking. As for hookah use, 14.9% believed it posed a lower risk than cigarettes. More than a third of trainees did not acknowledge the risks of passive e-cigarette use (42.9%) or hookah smoking (35.1%). Also, 32.4% endorsed e-cigarettes to quit smoking, whereas 22.5% felt ill equipped to discuss these tobacco products with patients. Fewer than half recalled attending lectures on these topics, and their most common sources of information were social media (54.5%), Google (40.8%), and friends and relatives (40.3%). CONCLUSIONS: Medical trainees often reported incorrect or biased perceptions of e-cigarettes and hookah, resorted to unreliable sources of information, and lacked the confidence to discuss the topic with patients. An expanded curriculum emphasis on e-cigarette and hookah use might be necessary because failing to address these educational gaps could risk years of efforts against smoking normalization.

RESUMO

The increased use of E-cigarettes and hookah among young consumers represents a public health concern. This study aimed to investigate the frequency and patterns of use of E-cigarettes and hookah among medical trainees. This cross-sectional multinational online survey included medical students, residents, and fellows in Brazil, the U.S., and India between October 2020 and November 2021. Information on sociodemographics; mental health; and E-cigarettes, hookah, tobacco, marijuana, and alcohol use were collected. Generalized structural equation models were used in 2022 to explore the factors associated with current vaping and current hookah use (ongoing monthly/weekly/daily use). People reporting previous sporadic/frequent use or those who never used/only tried it once were the reference group. Overall, 7,526 participants were recruited (Brazil=3,093; U.S.=3,067; India=1,366). The frequency of current vaping was 20% (Brazil), 11% (U.S.), and <1% (India), and current hookah use was 10% (Brazil), 6% (U.S.), and 1% (India). Higher family income (OR=6.35, 95% CI=4.42, 9.12), smoking cigarettes (OR=5.88, 95% CI=4.88, 7.09) and marijuana (OR=2.8, 95% CI=2.35, 3.34), and binge drinking (OR=3.03, 95% CI=2.56, 3.59) were associated with current vaping. The same was true for hookah use: higher family income (OR=2.69, 95% CI=1.75, 4.14), smoking cigarettes (OR=3.20, 95% CI=2.53, 4.06), smoking marijuana (OR=4.17, 95% CI=3.35, 4.19), and binge drinking (OR=2.42, 95% CI=1.96, 2.99). In conclusion, E-cigarettes and hookah were frequently used by Brazilian and American trainees, sharply contrasting with data from India. Cultural aspects and public health policies may explain the differences among countries. Addressing the problems of hookah and E-cigarette smoking in this population is relevant to avoid the renormalization of smoking.

RESUMO

There is an urgent need for an ethical framework to help us address the local and national challenges that we face as clinicians during the COVID-19 pandemic. We propose four key commitments from which a practical and consistent ethical approach can be derived. These commitments are to articulate the needs, rights and interests of the different stakeholders affected by any policy; to be accountable and transparent, recognising that people are autonomous individuals with values and concerns of their own; to consider the impact of our actions on the sustainability of the NHS, infrastructure, service demands and staff welfare; and to treat everybody equitably, with all deserving of consideration and care. Implementing these commitments will require a number of specific actions. We must put in place frameworks enabling clear advocacy for each competing objective; communicate policy and practice effectively to the public; promote integration of decision-making among social, primary, secondary and tertiary care and reduce or stop unnecessary or inefficient interventions; minimise health inequalities; and build spare capacity into the system.In this article, we expand on these actions, and note the legal context in which this would be delivered.

RESUMO

OBJECTIVE: To determine whether discussion and documentation of decisions about future care was improved following the introduction of a new approach to recording treatment decisions: the Universal Form of Treatment Options (UFTO). METHODS: Retrospective review of the medical records of patients who died within 90 days of admission to oncology or respiratory medicine wards over two 3-month periods, preimplementation and postimplementation of the UFTO. A sample size of 70 per group was required to provide 80% power to observe a change from 15% to 35% in discussion or documentation of advance care planning (ACP), using a two-sided test at the 5% significance level. RESULTS: On the oncology ward, introduction of the UFTO was associated with a statistically significant increase in cardiopulmonary resuscitation decisions documented for patients (pre-UFTO 52% to post-UFTO 77%, p=0.01) and an increase in discussions regarding ACP (pre-UFTO 27%, post-UFTO 49%, p=0.03). There were no demonstrable changes in practice on the respiratory ward. Only one patient came into hospital with a formal ACP document. CONCLUSIONS: Despite patients' proximity to the end-of-life, there was limited documentation of ACP and almost no evidence of formalised ACP. The introduction of the UFTO was associated with a change in practice on the oncology ward but this was not observed for respiratory patients. A new approach to recording treatment decisions may contribute to improving discussion and documentation about future care but further work is needed to ensure that all patients' preferences for treatment and care at the end-of-life are known.

RESUMO

BACKGROUND: COPD has significant psychosocial impact. Self-management support improves quality of life, but programs are not universally available. IT-based self-management interventions can provide home-based support, but have mixed results. We conducted a case series of an off-the-shelf Internet-based health-promotion program, The Preventive Plan (TPP), coupled with nurse-coach support, which aimed to increase patient activation and provide self-management benefits. MATERIALS AND METHODS: A total of 19 COPD patients were recruited, and 14 completed 3-month follow-up in two groups: groups 1 and 2 with more and less advanced COPD, respectively. Change in patient activation was determined with paired t-tests and Wilcoxon signed-rank tests. Benefits and user experience were explored in semistructured interviews, analyzed thematically. RESULTS: Only group 1 improved significantly in activation, from a lower baseline than group 2; group 1 also improved significantly in mastery and anxiety. Both groups felt significantly more informed about COPD and reported physical functioning improvements. Group 1 reported improvements in mood and confidence. Overall, group 2 reported fewer benefits than group 1. Both groups valued nurse-coach support; for group 1, it was more important than TPP in building confidence to self-manage. The design of TPP and lack of motivation to use IT were barriers to use, but disease severity and poor IT skills were not. DISCUSSION: Our findings demonstrate the feasibility of combining nurse-coach support aligned to an Internet-based health resource, TPP, in COPD and provide learning about the challenges of such an approach and the importance of the nurse-coach role.

RESUMO

Soliciting a patient's agenda (the reason for their visit, concerns and expectations) is fundamental to health care but if not done effectively outcomes can be adversely affected. Forms to help patients consider important issues prior to a consultation have been tested with mixed results. We hypothesized that using an agenda form would impact the extent to which patients felt their doctor discussed the issues that were important to them. Patients were randomized to receive an agenda form to complete whilst waiting or usual care. The primary outcome measure was the proportion of patients agreeing with the statement 'My doctor discussed the issues that were important to me' rated on a four-point scale. Secondary outcomes included other experience and satisfaction measures, consultation duration and patient confidence. There was no significant effect of agenda form use on primary or secondary outcomes. Post hoc exploratory analyses suggested possible differential effects for new compared to follow-up patients. There was no overall benefit from the form and a risk of detrimental impact on patient experience for some patients. There is a need for greater understanding of what works for whom in supporting patients to get the most from their consultation.

RESUMO

RATIONALE AIMS AND OBJECTIVES: Problems exist with Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) orders: they are often misinterpreted by clinicians to mean that other treatments should be withheld; resuscitation decision discussions are difficult; patients remain inappropriately for resuscitation. We developed an alternative approach. METHODS: An adapted Delphi method was used. Senior clinicians were interviewed about the strengths and weakness of current practice. Teams who had initiated alternative approaches internationally were contacted. Focus groups were conducted with doctors, nurses and patients to further understand problems with DNACPR orders and establish essential aspects of a new approach. A behavioral economist and management consultant contributed advice. The resulting form was recirculated and further refined. It was: snowballed out to others with specialist expertise (palliative care physicians, intensivists, etc) for further feedback; assessed in simulated clinical encounters before being piloted; further adjusted once in clinical practice. In parallel, a patient information leaflet was developed along with education materials. RESULTS: Consensus was achieved that the new approach should: be universal; have discussions and clinical conditions documented first; clarify goals of overall treatment (active treatment or optimal supportive care); contextualize the resuscitation decision among other treatment decisions; have a free text box for 'opting out' of invasive treatments, rather than tick boxes; be green; be limited to one page. CONCLUSIONS: The Universal Form of Treatment Options was developed iteratively with patients, doctors and nurses as an alternative approach to resuscitation decisions. This paper illustrates a cross-disciplinary approach to developing practical alternatives in health care.

RESUMO

AIMS: To establish the characteristics and outcomes of patients with Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) orders; to assess whether particular patient characteristics are associated with discussing resuscitation orders with patients. METHODS: Retrospective case note analysis from an acute hospital in 2009 was performed on: all in-hospital deaths; all patients who had carbon-copies of their DNACPR forms returned to the resuscitation department and a sample of age-matched discharged patients without known DNACPR order forms. Univariate and multivariate logistic regression analysis was used to test the significance of the associations and calculate odds ratios. RESULTS: Of 541 sampled patients, 51% of patients with DNACPR orders were discharged. Baseline characteristics of those who had in-hospital deaths or were discharged with DNACPR orders were similar. The overall one-year mortality for patients with a DNACPR order was 83%. 50% of patients had documentation of having DNACPR orders discussed: this was consistent across patient characteristics including those who were discharged and those who had in-hospital deaths. Cases of "inappropriate" resuscitation attempts were identified. CONCLUSIONS: About half of patients with DNACPR orders were discharged home, and 17% were alive at one year. Characteristics of patients and frequency of discussions were similar in those who died or were discharged. Current focus of use of DNACPR orders only on those identified as most likely to die makes inappropriate resuscitation attempt a likely occurrence, and care is required to ensure conflation with "end of life" pathways does not distort the treatments given to this vulnerable group.

RESUMO

AIMS: To determine whether the introduction of the Universal Form of Treatment Options (the UFTO), as an alternative approach to Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) orders, reduces harms in patients in whom a decision not to attempt cardiopulmonary resuscitation (CPR) was made, and to understand the mechanism for any observed change. METHODS: A mixed-methods before-and-after study with contemporaneous case controls was conducted in an acute hospital. We examined DNACPR (103 patients with DNACPR orders in 530 admissions) and UFTO (118 decisions not to attempt resuscitation in 560 admissions) practice. The Global Trigger Tool was used to quantify harms. Qualitative interviews and observations were used to understand mechanisms and effects. RESULTS: RATE OF HARMS IN PATIENTS FOR WHOM THERE WAS A DOCUMENTED DECISION NOT TO ATTEMPT CPR WAS REDUCED: Rate difference per 1000 patient-days was 12.9 (95% CI: 2.6-23.2, p-value=0.01). There was a difference in the proportion of harms contributing to patient death in the two periods (23/71 in the DNACPR period to 4/44 in the UFTO period (95% CI 7.8-36.1, p-value=0.006). Significant differences were maintained after adjustment for known confounders. No significant change was seen on contemporaneous case control wards. Interviews with clinicians and observation of ward practice revealed the UFTO helped provide clarity of goals of care and reduced negative associations with resuscitation decisions. CONCLUSIONS: Introducing the UFTO was associated with a significant reduction in harmful events in patients in whom a decision not to attempt CPR had been made. Coupled with supportive qualitative evidence, this indicates the UFTO improved care for this vulnerable group.

RESUMO

OBJECTIVE: We wished to evaluate the effects of inhaled formoterol, a long-acting beta(2)-adrenergic agonist, on exercise tolerance and dynamic hyperinflation (DH) in severely disabled chronic obstructive pulmonary disease (COPD) patients. DESIGN: In a two-period, crossover study, 21 patients with advanced COPD (FEV(1)=38.8+/-11.7% predicted, 16 patients GOLD stages III-IV) were randomly allocated to receive inhaled formoterol fumarate 12 microg twice daily for 14 days followed by placebo for 14 days, or vice versa. Patients performed constant work-rate cardiopulmonary exercise tests to the limit of tolerance (Tlim) on a cycle ergometer: inspiratory capacity (IC) was obtained at rest and each minute during exercise. Baseline and transitional dyspnoea indices (BDI and TDI) were also recorded. RESULTS: Eighteen patients completed both treatment periods. Formoterol treatment was associated with an estimated increase of 130 s in Tlim compared with placebo (P=0.052): this corresponded to a 37.8% improvement over placebo (P=0.012). Enhanced exercise tolerance after bronchodilator was associated with diminished DH marked by higher inspiratory reserve and tidal volumes at isotime and exercise cessation (P<0.05). There was no significant difference between formoterol and placebo on exercise dyspnoea ratings; however, all domains of the TDI improved (P

RESUMO

OBJECTIVE: Whole-body plethysmography is a common method of measuring pulmonary function. Although this technique provides a sensitive measure of pulmonary function, it can be problematic and unsuitable in some patients. The development of more accessible techniques would be beneficial. METHODS: A prospective study was performed to validate diaphragm ultrasonography as an alternative to whole-body plethysmography in patients referred for pulmonary function testing. Diaphragm movement and position were assessed by ultrasonography after standard pulmonary function testing using whole-body plethysmography. RESULTS: A wide range of lung function was observed. Standard lung volumes were as follows: total lung capacity, 5.57 +/- 1.31 L, residual volume, 2.27 +/- 0.56 L; and vital capacity, 3.30 +/- 0.98 L (mean +/- SD). The ratio of forced expiratory volume in 1 second to forced vital capacity was calculated as 0.69 +/- 0.08. Ultrasonography showed that mean diaphragm excursion values were 11.1 +/- 3.8 mm (2-dimensional), 14.7 +/- 4.1 mm during quiet breathing (M-mode), and 14.8 +/- 3.9 mm during a maximal sniff (M-mode). The velocity of diaphragm movement rose sharply during the sniff maneuver from 15.2 +/- 5.8 mm/s during quiet breathing to 104.0 +/- 33.4 mm/s. Static 2-dimensional measures of diaphragm position at the end of quiet inspiration or expiration correlated with standard measures of lung volume on plethysmography (eg, a correlation coefficient of 0.83 was obtained with end inspiration and vital capacity). All measures of diaphragm movement (whether by 2-dimensional or M-mode techniques) were poorly correlated with any lung volumes measured. CONCLUSIONS: These data suggest that dynamic measurements using diaphragm ultrasonography provide a relatively poor measure of pulmonary function in relation to whole-body plethysmography.

RESUMO

STUDY OBJECTIVE: s: Patients with rheumatoid arthritis (RA) have a high prevalence of pulmonary function test (PFT) abnormality, but the long-term significance of this is unknown. We performed a longitudinal study of pulmonary function in asymptomatic, nonsmoking patients with active RA requiring disease-modifying drugs. We looked for temporal change in lung function and characteristics that would predict subsequent development of PFT abnormality or respiratory symptoms. METHODS: In 1990, 52 patients (44 women; age range, 29 to 78 years; median, 56 years) underwent clinical assessment (drug history, RA severity, immunologic, and inflammatory markers) and PFTs (spirometry, body plethysmography, gas transfer). PFT results were expressed as standardized residuals (SRs). Thirty-eight patients were reassessed in 2000. A self-administered questionnaire was used to identify respiratory symptoms. RESULTS: The prevalence of pulmonary function abnormality was higher than expected compared with a reference population, but there was no significant increase in number over 10 years (8.7% in 1990 and 8.8% in 2000). When assessed by group means and compared with reference values, reduced diffusing capacity of the lung for carbon monoxide (DLCO) and increased ratio of residual volume (RV) to total lung capacity (TLC) [RV/TLC] were the only abnormalities to develop over the study period (mean DLCO in 2000, - 0.47 SR; 95% confidence interval [CI], - 0.91 to - 0.01; RV/TLC, 0.49 SR; 95% CI, 0.13 to 0.84). However, rates of change of pulmonary function variables were not significantly different from zero. Logistic regression did not identify any meaningful relationship between disease characteristics and PFT abnormality. CONCLUSIONS: Asymptomatic patients with RA have a higher prevalence of PFT abnormality than expected, but these do not increase in number over time. We did not identify any patient or disease-specific characteristic that could predict the development of respiratory disease in patients with RA. Analysis using percentage of predicted values, rather than SRs, is misleading as it exaggerates the extent of abnormality present. Abnormal lung function is a common and probably benign finding in nonsmoking, asymptomatic patients with RA.

RESUMO

BACKGROUND: Evaluation of fat-free mass (FFM) is becoming recognised as an important component in the assessment of clinical status and formulation of prognosis in patients with chronic obstructive pulmonary disease (COPD). OBJECTIVE: The aim of this study was to determine whether potential differences in FFM estimation performed by air displacement plethysmography (ADP), bioelectrical impedance (BIE) and anthropometry (ANTHRO) would assume clinical significance. METHODS: Twenty-eight patients with moderate-to-severe COPD were submitted to FFM estimation by ADP, BIE and ANTHRO. FFM was then allometrically related to peak oxygen uptake (peak VO2) as determined by symptom-limited incremental cycle ergometry. RESULTS: We found that ANTHRO classified fewer patients as 'FFM-depleted' than the other two techniques (p < 0.05). Although mean biases of the BIE-ADP differences were close to zero, their 95% confidence limits extended as high as 5.9 kg (16%). The ANTHRO-based allometric exponents for peak VO2 correction of FFM, therefore, were typically higher than those obtained by the other two methods in both depleted and non-depleted patients (ANTHRO: 1.45-1.41, BIE: 0.97-1.18, ADP: 1.08-1.14, respectively). CONCLUSION: We conclude that between-method differences in FFM estimation can be sufficiently large to have practical implications in patients with moderate-to-severe COPD. A single method of body composition assessment, therefore, should be used for FFM estimation in these patients.
