Code Status: What does it mean? Sheila Modi Best Practices Meeting November 16, 2011 Objectives Assess current beliefs Define “Code Status” Discuss barriers to appropriate use of code status Discuss possible changes to our current system of discussing and documenting code status. Question 1 An 80 yo F with HTN, hypothyroidism with code status DNR comes to the ED c/o dizziness, SOB, and rapidly deteriorating (unstable) condition. She is unable to talk to you. Cardiac monitoring reveals SVT. Should you: Cardiovert her. B. Do not perform any electrical shocks, even if this results in her death. C. Not enough information. A. Question 2 A 68 yo F with asthma and metastatic breast cancer with a code status of DNR comes in with an asthma exacerbation triggered by an accidental exposure to a cat. She has impending respiratory failure. Should you: Intubate her. B. Do not intubate her, even if this results in her death. C. Not enough information. A. Question 3 A 75 yo M with severe COPD (FEV1 0.7) with a code status of DNR comes in with a COPD exacerbation and has impending respiratory failure. Should you: Intubate him. B. Do not intubate him, even if this results in his death. C. Note enough information. A. Question 4 A 60 yo M with HTN, DM2, and CAD with a code status of DNR comes in with severe multi-lobar PNA and has impending respiratory failure. Should you: Intubate him. B. Do not intubate him, even if this results in his death. C. Not enough information. A. Question 5 A 70 yo M with HTN, CKD, CAD, PAD, DM2, and now MRSA PNA and bacteremia who has a documented code status of DNR is on the SAC floor being treated with Vancomycin. Despite abx, his condition deteriorates and he develops septic shock and respiratory distress. He is febrile 39C, hypotensive 85/55, tachycardic 115, tachypneic 28, and his breathing is labored with accessory muscle use. He has not responded to 3L NS. MICU (you) are called to evaluate. When you arrive, patient’s mental status has deteriorated and he is no longer able to coherently answer questions. Should you: A. B. C. D. Admit to MICU, continue Vancomycin, place central line, start vasopressors, intubate and place on mechanical ventilation. Admit to MICU, continue Vancomycin, place central line, start vasopressors, but do not intubate. Do not admit to MICU as patient has already indicated he does not want these aggressive interventions, even if this results in his death. Not enough information. ANSWERS: Not enough information! Do we really know what code status signifies? A survey of 3rd year medical students revealed: 100% reported they knew what code status means Only 17% reported an “excellent understanding”. My interpretation of these findings: they didn’t really know what it means Not knowing what code status means is a barrier to appropriate use Code Status Designation of whether or not to perform resuscitation in the event of cardiac and/or respiratory arrest. Code status holds NO significance in the pre-arrest period Should NOT influence other theraputic interventions that may be appropriate for patient Other life-sustaining therapies include: intubation and mechanical ventilation, pressors, ICU transfer, antibiotics, IV fluids, artificial nutrition Intubation should always be addressed separately, especially in patients with DNR orders Should address the difference between intubating for respiratory insufficiency and intubating during a cardiac arrest Pre-arrest period Pre-arrest period may include failing heart and/or ineffective breathing; and may lead to cardiac or respiratory arrest if management fails Pre-arrest period scenarios include managing dysrhythmias, ventilatory insufficiency, ineffective gas exchange, respiratory failure Use of ACLS protocols is not limited to cardiac and respiratory arrest situations; they are also used in the management of pre-arrest conditions and adverse clinical events. Advance Directives Don’t really help much because it is often difficult to ascertain when the wishes stated in the advance directive apply and because the wishes indicated are at times too vague to be useful in decision-making They often fail to take into account a person’s specific medical condition So, it is still important to have code status discussion at each admission Code status designation is valid only for single hospitalization; should be re-addressed each time Partial DNR orders: A hazard to patient safety and clinical outcomes? The practice is clinically and ethically problematic Respect for patient autonomy may create the potential for patient harm Medical treatments are often performed in groupings in order to work effectively. When such combinations are separated as a result of patient choices, critical elements of life-saving care may be omitted, and the patient may receive non-beneficial or harmful treatment. A “slow code” is ALWAYS unethical (not intended to be theraputic so is non- beneficial and is misleading to the decision-maker) Partial DNR orders A partial DNR order highlights larger problems: Misunderstanding of the meaning/scope of a DNR order Moral hazard: providers may inadvertently withhold treatments that are not considered part of a DNR order. This may be inconsistent with patient preferences. Need for discussions around goals of care Does DNR status affect clinical care? It should NOT, but studies have shown that it does. This is a barrier to patients choosing DNR status Studies have found that interpretations of what a DNR order means vary considerably between physicians, with implications for the overall course of treatment. Beach, MC and Morrison RS. The Effect of Do-NotResuscitate Orders on Physician Decision Making A survey involving 3 hypothetical clinical vignettes involving cases with serious life-threatening illnesses was distributed. A series of 10 sequential treatment decisions followed each vignette. Using a 4 point Likert scale, respondents were asked to indicate whether they would initiate these interventions. There were 2 versions of the survey, in one version the patients all had DNR orders. Physicians agreed or strongly agreed to initiate fewer interventions when a DNR order was present vs. absent •Physicians agreed to initiate fewer interventions when DNR order in place. •Case Mr. M: 4.2 vs 5.0 (p=.008) •Case Mrs. T: 6.5 vs 7.1 (p=.004) •Case Mr. H: 5.7 vs 6.2 (p=.037) •A decrease of 1.0 on this scale represents a 12.5% decrease in the number of interventions that the physicians would initiate. •“The results support the hypothesis that, when presented with identical patient scenarios, physicians will withhold treatments other than CPR for patients with DNR orders.” •Limitation of study: “Not enough information” was not an option in the survey. Chen, J.L.T., et al. Impact of do-not-resuscitation orders on quality of care performance measures in patients hospitalized with acute heart failure. Retrospective chart review looking at HF performance measures stratified according to the presence of DNR orders. HF performance measures included: Assessment of LV function Use of ACE/ARBs Anticoagulation (if atrial fibrillation present) Smoking cessation counseling Use of nonpharmacologic strategies, e.g. fluid restriction, diet, alcohol, and exercise. Conclusion: Patients with DNR orders were less likely to receive diagnostic and treatment therapies for HF according to the ACC/AHA quality measure guidelines. Code status should never be used for broader interpretation Multiple studies have shown that physicians’ ability to predict patient preferences regarding LST based on code status is no better than chance We will not know unless we also ask questions about preferences for LST Appropriate Code Status/LST Discussion Build trust, rapport Framed in terms of the overall goals of care Distinguish between LST and CPR Patient-specific information Diagnosis, treatment, prognosis Should educate patient on prognosis of CPR (future slide) Make a recommendation This takes time! Code status Discussions Kaldjian, L.C., et. al. Code status discussions and goals of care among hospitalized adults. 135 pts interviewed within 48h of admission to a general medicine service 41 (30.4%) pts had discussed code status with their physician 116 (85.9%) preferred Full code 11 (8.1%) patients expressed code status preferences different from the code status documented in their medical record. Most patients believed it was helpful to discuss goals of care and the chances of surviving in-hospital CPR 11 (8.1%) pts changed their code status after receiving information about survival following in-hospital CPR 2 (1.5%) pts changed their code status after discussing goals of care Appropriate Code Status/LST Discussion Build trust, rapport Framed in terms of the overall goals of care Distinguish between LST and CPR Patient-specific information Diagnosis, treatment, prognosis Should educate patient on prognosis of CPR (next slide) Make a recommendation This takes time! Prognosis after CPR Studies show that ~15% pts given CPR survive until hospital discharge Although ~40% survive the initial CPR attempt Prognosis depends on underlying medical conditions One study showed that in pts with renal failure only 2% survived until discharge Another study showed that in pts with metastatic cancer, none survived until discharge With sepsis, only 1% survived until discharge No survivors to discharge if CPR lasted >30 min One study found that 11% of pts who survive initial CPR will undergo CPR at least one other time during hospitalization Those who do survive to discharge usually do not have severe impairment (were AAOx3), but all had decrease in functional status Of those who survive to discharge, 25% survive >5 years Factors for Favorable Prognosis after CPR: Healthy baseline;Younger age; Witnessed arrest; Initial rhythm of v-fib; CPR lasted <10 min; Respiratory arrest (as opposed to cardiac arrest) Prognosis with Partial DNR orders One study compared patients who received partial resuscitation to those who received full resuscitation. 23% (104/445 pts) who received full resuscitation survived until discharge No patients who received partial resuscitation survived until discharge (0/37 pts) Partial resuscitation included performing some resuscitative measures while withholding others (24 pts)AND performing all resuscitative efforts for a specified limited time (13 pts) Prognosis after Mechanical Ventilation Many pts fear intubation b/c they are unaware of the successful use of short-term mechanical ventilation in certain clinical situations Studies suggest the most influential factor in survival to discharge for patients with respiratory insufficiency is presence of significant comorbidities One study stratified pts on Charlson Comorbidity Index: group 1 scored </= 3; group 2 scored >3 Group 1: 94.4% were discharged home within 6 months Group 2: 23.4% survived until discharge Appropriate Code Status/LST Discussion Build trust, rapport Framed in terms of the overall goals of care Distinguish between LST and CPR Patient-specific information Diagnosis, treatment, prognosis Should educate patient on prognosis of CPR (future slide) Make a recommendation This takes time! Time Anderson, W.G, et. al. Code Status Discussions Between Attending Hospitalist Physicians and Medical Patients at Hospital Admission Observational study via audio-recordings of 80 pts admission encounters with 27 physicians at 2 hospitals The median length of the code status discussion was 1 min (range 0.2-8.2 min) Time constraint is a barrier to adequate discussion Time Roter, D.L., et. al. Experts Practice What They Preach: A Descriptive study of Best and Normative Practices in End-ofLife Discussions. Observational, audio-recordings of outpatient encounters Experts spent close to twice as much time (14.7 min vs 8.1 min, P<0.001) Experts were less verbally dominant (P<0.05) Experts gave less information about procedures and biomedical issues (P<0.05) Experts engaged more in partnership building (P<0.05) and in more psychosocial and lifestyle discussion (P<0.001) and in more positive talk (P<0.05) Time Loertscher, L.L., et. al. Code status discussions: agreement between internal medicine residents and hospitalized patients. 41 matched pairs (patients and admitting residents) Residents and patients agreed that a code status conversation occurred in 63% of cases Agreement was more likely if residents performed less than 4 admissions (P=0.02) Patients reported the inclusion of specific discussion components less frequently than residents (P<0.001) Resuscitation procedures (pts 7% vs residents 71%) Outcomes (0% vs. 27%) Time Deep, K.S., et. al. Discussing preferences for cardiopulmonary resuscitation: What do resident physicians and their hospitalized patients think was decided? Resident physicians, patients + family interviewed following discussion on code status 56 interviews, 28 matched pairs In 21% (6/28 pairs), participants reported differing results of the discussion 2 patients did not recall having the discussion Education Multiple studies show that students and residents receive minimal education on code status and how to have the discussion This is a barrier One study looked at 2 academic medical centers, one of which provided education to residents about patient care plans for patients with DNR orders The one with education had more comprehensive plans The effect of this education was sustained for 3 years after the education was given Review of Objectives Code status - defined Barriers to appropriate use of code status Don’t know definition/scope Partial DNR orders Code status has been shown to mean “less care” Time Education of students and residents Suggested intervention POLST Physician Orders for Life Sustaining Therapy Expands upon CPR status orders to include orders based on preferences about a range of life-sustaining treatments Form has orders including: Code status (CPR status) Medical interventions Hospitalization May include antibiotic use Artificial nutrition Form is printed on brightly colored card This standardized medical order form transfers across care settings Emergency services, hospitals, primary care practices, hospices, and nursing facilities POLST Program was developed in Oregon to overcome the limitations of advance directives and code status Now also used in other states www.polst.org Hickman, SE, et. al. A Comparison of Methods to Communicate Treatment Preferences in Nursing Facilities: Traditional Practices versus the Physician Orders for Life-Sustaining Treatment Program. Compare POLST vs. traditional practices Communication of treatment preferences Documentation of LST orders Symptom assessment and management Use of LST Retrospective observational cohort study; looking at residents in nursing facilities Hickman SE, et. al. A Comparison of Methods to Communicate Treatment Preferences in Nursing Facilities: Traditional Practices versus the Physician Orders for Life-Sustaining Treatment Program. Results: Residents with POLST were more likely to have orders about LST preferences beyond CPR than residents without (98.0% vs 16.1%, P<0.001) No difference between residents with and without POLST in symptom assessment or management Residents with POLST forms indicating comfort measures only were less likely to receive medical interventions (e.g. hospitalization) than residents with POLST forms indicating full treatment (P=0.004) or residents with traditional DNR orders (P<0.001) or residents with traditional Full code orders (P<0.001). Hickman, SE, et. al. A Comparison of Methods to Communicate Treatment Preferences in Nursing Facilities: Traditional Practices versus the Physician Orders for Life-Sustaining Treatment Program. Discussion: POLST orders were not associated with the use of antibiotics, despite specific orders addressing abx use. These findings suggest that the use of standing orders to prospectively make decisions about antibiotics may be an ineffective strategy, perhaps because there is substantial variability in interpretation of when antibiotics should be used to enhance comfort. Conclusion: Findings suggest that the POLST program offers significant advantages over traditional methods to communicate preferences about LST. Hickman SE, et. al. Use of the Physician Orders for LifeSustaining Treatment Program in Oregon Nurstin Facilities: Beyond Resuscitation Status Telephone survey and on-site POLST form review Oregon nursing facilities Results: 71% facilities reported using POLST for at least half of their residents DNR orders present on 88% of POLST forms On forms indicating DNR, 77% reflected preferences for more than the lowest level of treatment in at least one other category. On forms indicating Full code, 47% reflected preferences for less than the highest level of treatment in at least one other category. The oldest old (>/= 85 yrs) were more likely than the young old (65-74 yrs) to have orders to limit resuscitation, medical treatment, artificial nutrition and hydration. My Recommendations Implement POLST in New Mexico Do not include section for antibiotic use Provide more education to everyone Would be necessary in order to implement POLST anyway Do not allow partial DNR orders DISCUSSION References 1.
