E se fosse sua mãe, doutor?


"Me fale mais sobre sua mãe"

O texto abaixo é uma aula de empatia. Muitos tendem a pensar em empatia como "fazer aos outros exatamente aquilo que gostariam que fosse feito a si." Apesar parecer sempre altruístico, pode trazer uma armadilha, fruto de uma despercebida e muitas vezes não intencional crença de que aquilo que julgamos ser melhor para nós, certamente o será para os outros... Será que os quereres dos outros seguem o nosso gosto? Será que suas rezas seguem a nossa cartilha?

Vejam a abordagem madura de um residente

'If This Were Your Mother, Doctor…'

By HAIDER JAVED WARRAICH, M.D.
The other residents and I sat in our blue scrubs with our attending physician in the windowless family meeting room just outside the intensive care unit. We had gathered around one end of the ovoid table with the family of the patient, two daughters and a son, at the other.
The patient was an elderly woman, admitted to our unit just a few hours earlier, with a breathing machine keeping her alive. We proceeded with the meeting as we were trained to do. We kept our elbows off the table, maintained eye contact (but not too much) and gave the family an update of where we stood.
A healthy family meeting, we'd been told, involved us speaking for about half the time, with the family speaking for the rest – venting, questioning, grieving and hoping, in no particular order. This meeting, though, was dominated by long periods of silence that unearthed the dull, low-pitched drone in the background.
The son, quiet for most of the meeting, broke the silence and, with a hint of anger and a big dollop of frustration, asked the one question I had dreaded being asked the most: "Doc, give it to me straight. If this were your mother, what would you do?"
While the patient-doctor interaction varies widely across cultures and continents, this question seems to be a universal constant. As a medical student in Pakistan, I had heard it often, and even after hours of preparation, never felt prepared to answer. As a wobbly newcomer to clinical medicine, it left me feeling vulnerable and violated.
From a patient or family member's perspective, though, this question helps them make sense of the confusion, desolation and powerlessness that so often defines the hospital experience, which usually involves a full-on assault of numbers, jargon and 'expert' opinion. They are confronted with difficult choices, like whether they want to go ahead with a particular high-risk procedure or wait for the tincture of time to kick in.
Overwhelmed and confused, it makes sense that they would defer the choice to those who appear to know what they are doing. And by invoking the physician's parent, they hope to humanize the physician and have a conversation with real stakes.
Yet I still find this question hard to answer. See, my mother is the sort of person who spends two hours each day on the treadmill, even during vacations, so that she can eat to her heart's content. Often described as a "fighter," any additional moment she can spend with her children or future grandchildren would be worth the extra mile. My father, on the other hand, is someone who avoids getting his blood sugar level tested to evade medications and dreams of spending his last days in the quiet serenity of the village he grew up in. Thus my answer to the question would be very different, as it would be for anyone, depending on which parent you asked me about.
So I have come to believe that the right answer to the question, "If this were your mother, doctor…" is: "Tell me more about your mother."
This response gives patients' families the chance to think about their loved ones, about what they would value and what they would consider a good life, what they would think was worth fighting for if they were available to answer the question for themselves.
The burden that family members feel when making medical decisions as proxies is immense, whether a loved one has dementia or is so sick or confused that she can't participate meaningfully in decision making. But this response often helps to diffuse that. It takes them away from a place where they feel solely responsible for the trajectory of their relative's life to one where they simply communicate what the patient would want out of her life. We as physicians can then weigh in on whether it is reasonable to expect that to happen.
So I asked the family sitting across the table from me, "Tell me more about your mother."
And then, slowly, the family started sharing stories of the woman we had met only a few hours before, unconscious and intubated. She loved being independent, would hate for people to open doors for her or hold her hand as she tried to get up, they told us. She loved the sun, the beach. She loved walking, loved being out and about. She would never, ever want to go to a nursing home. Never ever. They pulled out a picture of her lounging on a chair, sipping lemonade.
We then told them that based on a combination of her vital signs and lab values, as well as our clinical judgment, that while we could hope for some progress, it would likely not be enough to allow her any real shot at experiencing life outside a nursing facility again.
The daughters shared another glance with their brother. Their shoulders were now less tense, their eyes less teary. The room seemed to be filled with memories of a woman who had lived life well. They turned to us and asked us to make her comfortable, and to turn off the breathing machine.

    PROCESSO-CONSULTA Protocolo CREMEC nº 8979/2016
    ASSUNTO:
    Uso de Receituário do SUS em consultório particular
    RELATOR: Dr. Ivan de Araújo Moura Fé

     

    EMENTA: É considerada falta ética a utilização de formulários de instituições públicas para a prescrição ou a elaboração de atestado referente a fatos verificados no atendimento privado (artigo 82 do Código de Ética Médica).
    CONSULTA
    O consulente indaga ao CREMEC: "Tenho uma dúvida em relação a situação a seguir. Um médico atende tanto em serviço público como  em serviço particular. Considerando que um dos seus pacientes do serviço particular precisa fazer uso crônico de um dos Medicamentos de Alto Custo do SUS, mas não tem condições de pagar por tal medicamento por muito tempo. Quais são os problemas, do ponto de vista ético-legal, caso o médico prescreva em receituários do SUS, para que o paciente receba a medicação de graça?
    PARECER
    O ponto nodal da consulta ora em análise é a prescrição em consultório particular utilizando receituário do serviço público. Tal procedimento é vedado pelo Código de Ética Médica, em seu artigo 82, transcrito abaixo:
    Código de Ética Médica – Artigo 82 – É vedado ao médico – Usar formulários de instituições públicas para prescrever ou atestar fatos verificados na clínica privada.
    Em sua obra "Comentários ao Código de Ética Médica", 6ª Edição, 2010, o renomado mestre Genival Veloso de França afirma que utilizar formulários de instituições públicas no consultório particular não pode ser considerado conduta lícita, mas constitui transgressão administrativa e infração ética, por transmitir a impressão de que o ato do atendimento, seja pela prescrição ou pela formulação do atestado médico, ocorreu em instituição pública.
    Assim, embora possa ser vista como elogiável a preocupação do médico em assegurar que o paciente sob seus cuidados continue tomando a medicação indicada, o meio para alcançar esse objetivo terá que ser outro e não o referido pelo consulente, que poderá dar margem a procedimento administrativo no Conselho Regional de Medicina para apuração de possível infração às normas éticas da profissão médica.

    Lack of benefit of intraarticular glucocorticoid injections for knee osteoarthritis
    Although limited evidence suggests that intraarticular glucocorticoid injections for knee osteoarthritis (OA) may result in short-term pain relief, data for longer-term outcomes are less favorable. A randomized trial including 140 patients with symptomatic knee OA and ultrasound features of synovitis found that pain reduction was no different comparing injections of 40 mg triamcinolone acetonide with placebo every 12 weeks for two years [1]. Furthermore, two years of triamcinolone injections resulted in greater cartilage volume loss. These findings do not support intraarticular glucocorticoid injections in patients with symptomatic knee OA and are consistent with our practice. In addition, we discourage the use of serial injections (eg, every three months) due to progressive cartilage damage in knee OA patients.

    Quando e como se deve utilizar corticoide na febre de Chikungunya? Fase subaguda e crônica. Doses variam. Vejam fluxogramas compilados

    Afinal, quando e como se deve utilizar corticoide na febre de Chikungunya?

    A febre de Chikungunya apresenta três fases:
    • Aguda: do início dos sintomas até 14 dias
    • Subaguda: de 14 dias até 3 meses
    • Crônica: mais de 3 meses
    Com relação aos sintomas articulares, cerca de 75% permanecem sintomáticos após um mês e cerca de 50% após 3 meses, ou seja, na fase crônica da doença.

    Então quando utilizar corticoide?

    1. Não usar na fase aguda da doença (período febril ou com menos de 14 dias de doença)
    2. Não usar corticoides de depósito (Betatrinta, Diprospan etc)
    3. Utilizar nas fases subaguda e crônica da doença, em geral, após não responder ao tratamento com analgésicos, opióides fracos e antiinflamatórios (vejam os algoritmos abaixo)
    4. Utilizar de preferência a prednisona na dose de 10 a 20 mg/dia (recomendações da sociedade brasileira de reumatologia) ou até 0,5 mg/kg (manual de manejo do ministério da saúde).

    Distúrbios mentais estáveis não contra-indicam medicações para abandono de tabagismo



    Safety of smoking cessation medications in patients with and without mental health disorders
    Reports of newly emergent depression, suicidal ideation, and suicidal behavior among patients receiving bupropion or varenicline for smoking cessation raised questions about the safety of these drugs in smokers with mental health disorders. In a recent trial examining the safety of these medications, more than 8000 motivated adult smokers, approximately half with clinically stable mental health disorders, were randomly assigned to varenicline, bupropion, transdermal nicotine, or placebo for 12 weeks [1]. Compared with patients without mental health disorders, patients with such disorders were more likely to experience neuropsychiatric adverse events (including anxiety, depression, agitation, or hostility) during treatment (2.1 versus 5.8 percent). However, in both patients with and without mental health disorders, the rate of events did not differ for patients assigned to varenicline or bupropion compared with placebo. Rates of smoking abstinence were higher with each of the three drugs compared with placebo, and higher with varenicline compared with bupropion or transdermal nicotine. The findings are consistent with previous, smaller trials supporting carefully monitored use of smoking-cessation medications in smokers with stable mental health disorders.

    Parar de fumar: Melhor parar de uma vez que diminuir aos poucos


    Após decidir uma dada para parar de fumar, pacientes que param abruptamente parecem ter mais chance de sucesso do que os que diminuem até parar.


    Abrupt smoking cessation compared with gradual smoking reduction
    Earlier evidence from randomized trials had suggested that, after a quit date is set, abstinence rates were equivalent for patients who reduced smoking prior to the quit date or stopped smoking abruptly on the quit date. However, more recent studies suggest that among smokers who plan to quit in the near future, quit rates are higher for patients who stop abruptly. The most recent randomized trial included 697 smokers in England and found that gradual smoking cessation (decreasing by 75 percent in the two weeks prior to quitting) was associated with decreased likelihood of abstinence at four weeks when compared with abrupt smoking cessation (39 versus 49 percent) [1].
    See 'Overview of smoking cessation management in adults', section on 'Setting a quit date'.

    Corticoide para faringite aguda: pouco benefício, não prescrever de rotina


    De novo sobre corticoides...
    Estudo mostra benefícios modestos e lembremos dos efeitos colaterais

    Dexamethasone and acute pharyngitis pain in adults
    Studies of oral glucocorticoids for acute pharyngitis pain have generally found only modest benefit but have been limited by confounding factors such as concurrent antibiotic use. In an office-based randomized trial that compared a single dose of dexamethasone with placebo for adults who visited a primary care clinician for acute pharyngitis and were not given an immediate prescription for antibiotics, there was no difference in the proportion of patients who achieved full pain relief at 24 hours, and there was only a small difference in symptom relief at 48 hours (35 versus 27 percent with placebo) [2]. These results support our suggestion to not prescribe glucocorticoids routinely for acute pharyngitis and to limit their use to severely symptomatic patients.

    Mesmo cursos breves de corticoides: 2x mais fraturas, 3x mais TVP e 5x a chance de Sepse em um mês




    A prescrição de corticoides (e mesmo corticoides de depósito[!]) não tem sido incomum para alívio sintomático de quadros relativamente banais como infecções de vias aéreas sem maiores complicações e outras afecções como dores articulares leve e quadros inflamatórios diversos.




    A despeito da melhora sintomática importante que trazem, critérios judiciosos para a prescrição dessas medicações devem ser tomados, pois não são isentos de riscos! Lembrem-se do Dr. Otho: "O corticoide leva o paciente para a mesa de Laennec sorrindo".

    Segundo estudo do BMJ, no primeiro mês após uso de corticoides, há 2 vezes mais chances de fratura, 3 vezes mais chance de trombose venosa profunda e 5 vezes o risco de sepse. Esses eventos se manifestaram mesmo com 5-6 dias de curso e com doses de somente 20 mg equivalente de prednisona. 

    Vejam mais informações e link para o artigo abaixo.



    Even Short-term Oral Steroids Carry Serious Risk

    The millions of Americans prescribed short-term oral corticosteroids are taking a dose of risk along with their medication, according to a cohort study of more than 1.5 million adults.

    Within 30 days of initiating these drugs, even at relatively low doses, users had a nearly twofold increased risk for fracture, a threefold increased risk for venous thromboembolism, and a fivefold increased risk for sepsis.

    "Greater attention to initiating prescriptions of these drugs and monitoring for adverse events may potentially improve patient safety," write Akbar K. Waljee, MD, an assistant professor of gastroenterology at the University of Michigan in Ann Arbor, and colleagues. They present their findings in an article published April 12 in the BMJ.

    They found that more than one in five adults included in the Clinformatics DataMart, a large national database of commercial insurance claims, received prescriptions for short-term oral corticosteroids during the 3-year study, which ran from January 1, 2012, to December 31, 2014.

    Although corticosteroids are among the most common cause for hospitalization for drug-related adverse events, and various specialties have long focused on optimizing their long-term use, the short-term risks associated with the drugs have been less carefully studied.

    "Although physicians focus on the long-term consequences of steroids, they don't tend to think about potential risks from short-term use," said Dr Waljee in a university news release. "We see a clear signal of higher rates of these three serious events within 30 days of filling a prescription. We need to understand that steroids do have a real risk and that we may use them more than we really need to. This is so important because of how often these drugs are used."

    Of 1,548,945 adults aged 18 to 64 years included in the database, 327,452 (21.1%) received at least one outpatient prescription for short-term oral corticosteroids (30 or fewer days). The mean age of users was 45.5 years (standard deviation [SD], 11.6 years) compared with 44.1 years (SD, 12.2 years) for nonusers (P < .001). The median duration of use was 6 days (interquartile range, 6 - 12 days).

    The six most common indications for the drugs were upper respiratory tract infections, spinal conditions, intervertebral disc disorders, allergies, bronchitis, and nonbronchitic lower respiratory tract disorders. Together, those indications accounted for about half of all prescriptions. The two most common physician specialties prescribing short-term oral corticosteroids were family medicine and general internal medicine.

    Nearly half (46.9%) of recipients were prescribed a 6-day prepackaged methylprednisolone "dosepak," which tapers the dose from highest to lowest. Dr Waljee noted in the news release that although individual oral steroid pills can cost less than a dollar each for a 7-day course, the prepackaged version may cost several times that and often initiates therapy with a higher high dose than may be necessary.

    Use was more frequent among older patients, women, and white adults, with significant regional variation (all P < .001).

    Within 30 days of drug initiation, there was an increase in incidence rate of the following: sepsis, with a rate ratio of 5.30 (95% CI, 3.80 - 7.41); venous thromboembolism, with a rate ratio of 3.33 (95% CI, 2.78 - 3.99); and fracture, with a rate ratio of 1.87 (95% CI, 1.69 - 2.07).

    The increased risk persisted at prednisone equivalent doses of less than 20 mg/day, with an incidence rate ratio of 4.02 for sepsis, 3.61 for venous thromboembolism, and 1.83 for fracture (all P < .001).

    Rate ratios decreased during the following subsequent 31 to 90 days, however.

    Although rare, hospitalizations were also more frequent in users than nonusers, with 0.05% of users admitted for sepsis compared with 0.02% of nonusers. For blood clots, the admission rate was 0.14% versus 0.09%, and for fractures, it was 0.51% vs 0.39%.

    Dr Waljee and associates found it significant that the most frequent corticosteroid prescribers were not rheumatologists or other subspecialists experienced in treating inflammatory conditions long-term. "A substantial challenge to improving use of oral corticosteroids will be the diverse set of conditions and types of providers who administer these drugs in brief courses," they write. "This raises the need for early general medical education of clinicians about the potential risks of oral corticosteroids and the evidence basis for their use, given that use may not be specific to a particular disease or specialty."

    On the basis of these findings, Dr Waljee recommended prescribing the smallest possible amount of corticosteroids for treating the condition in question. "If there are alternatives to steroids, we should be use those when possible," he said in the release. "Steroids may work faster, but they aren't as risk-free as you might think."

    This study was supported partly supported by the University of Michigan's Institute for Healthcare Policy. The authors have disclosed no relevant financial interests.

    Hipotireoidismo subclínico em idosos: Tratar ou não tratar?

    Treatment with levothyroxine provides no symptomatic benefit in older adults with subclinical hypothyroidism
    Subclinical hypothyroidism is defined biochemically as an elevated serum thyroid-stimulating hormone (TSH) and a normal serum-free thyroxine (T4) level. Some patients with subclinical hypothyroidism may have vague, nonspecific symptoms. Although virtually all experts recommend treatment of subclinical hypothyroidism when serum TSH concentrations are ≥10 mU/L, treatment of patients with TSH values between the upper reference limit and 9.9 mU/L remains controversial, particularly in older patients who are more likely to have complications from unintended overtreatment. In a randomized trial evaluating the effect of levothyroxine versus placebo on quality of life measures in over 700 older patients (mean age 74.4 years) with mean TSH 6.4 mU/L, there was no difference in hypothyroid symptoms or tiredness scores after one year [2]. We do not routinely treat older patients with TSH between the upper reference limit and 9.9 mU/L (algorithm 1).

    Dicas para uso racional de sangue: O menos é mais na transfusão também! 1 CHF é melhor do que 2

    Caros,


    Durante este mês, faremos a divulgação da campanha do HEMOCE para transfusão segura de hemocomponentes! Peço que encaminhem e compartilhem para divulgação ampla de tema tão importante.


    Na primeira parte, seguindo o paradigma do "menos é mais", traz-se a seguinte recomendação:



    Realizar a transfusão de somente 1 (um) concentrado de hemácias por vez e REAVALIAR clinicamente ao invés de transfusões múltiplas no mesmo dia.


    De forma geral, o volume de hemácias transfundido deve ser somente o mínimo necessário a prevenir ou reverter a hipóxia tissular resultante da diminuição da massa eritrocitária, dessa forma garantindo a estabilidade hemodinâmica. Idealmente transfundir um concentrado a cada dia, de acordo com necessidade clínica, seguido de reavaliação. Ou seja, não há necessidade de normalização de índices hematimétricos à custa de politransfusões.

    Preferir também realizar a transfusão, quando possível, no período diurno, uma vez que tem-se maior vigilância com relação às reações transfusionais.

    Claro que existem situações clínicas específicas (politrauma, por exemplo) que necessitam de politransfusões, entretanto, a recomendação acima é para evitar múltiplas transfusões de forma rotineira, sem reavaliação clínica, guiando-se apenas por exames.

    Dica:

    Estima-se que cada 4 ml/kg de CHF elevam a Hb em 1 ponto e o Ht em 3%

    Farmacoterapia para tabagismo gestante: Pode?




    Pharmacotherapy for smoking cessation during pregnancy 
    Pregnant women are strongly encouraged to stop smoking, but the efficacy of pharmacotherapy for smoking cessation during pregnancy has been debated. In a prospective questionnaire study of over 1200 pregnant smokers, use of either nicotine replacement therapy (NRT) or bupropion in the first trimester of pregnancy was associated with smoking cessation rates of approximately 80 percent compared with a 0 percent cessation rate for smokers not using either medication [10]. Over 60 percent of NRT and bupropion users who discontinued the medication did not resume smoking during or up to one year after pregnancy. In adjusted analysis, both medications reduced the risk of prematurity and NRT was also associated with a nearly 40 percent reduced risk for small-for-gestational-age infants compared with continued smoking, although the sample sizes were small. We offer pharmacotherapy to pregnant women as we believe the benefits of quitting with pharmacotherapy outweigh the potential risks.
