Prehospital withholding and withdrawal of life-sustaining treatments. The French LATASAMU Survey

Relationship between cancer status and medical response by an emergency dispatch center: From a French SAMU database

OBJECTIVE

In many countries, the first line response to an emergency call is decided by the emergency dispatch center EMS clinician. Our main objective was to compare the pre-hospital response to calls received from cancer and non-cancer patients. We also compared the reasons for calling, for each group.

METHODS

We conducted a retrospective cohort study of data collected between January 1, 2016 and December 31, 2020, from emergency dispatch center records of the Isère county, France. Statistical tests were conducted after matching one cancer patient with two non-cancer patients, resulting in a cohort of 44,022 patients. We used multivariate logistic regression to determine the impact of patient cancer status on the medical decision taken in response to the emergency call.

RESULTS

Overall, data on 849,110 patients were extracted, including 16,451 patients with a diagnosis of cancer and 29,348 non-cancer patients. In the matched cohort, cancer was associated with a higher odd of having a mobile intensive care unit (MICU) [odds ratio (OR)=2.02 (1.81-2.26), p<0.001] or an ambulance being dispatched to the patient's home or other location [OR=2.36 (2.24-2.48), p<0.001]. The two most frequent medical responses were to send an ambulance (58.6%) and giving advice only (36.8%). The five main reasons for the emergency call for the cancer group were cardiovascular disease symptoms (13.5%), respiratory problems (10.6%), digestive disorders (10.4%), infections (8.9%) and neurological disorders (6.0%).

CONCLUSION

An MICU or an ambulance was more often dispatched for cancer patients than for others. Considering that cancer is a very frequent comorbidity in Western countries, knowledge of the patient's cancer status should be sought and taken into consideration when a patient seeks emergency help.

Advising and limiting medical treatment during phone consultation: a prospective multicentre study in HEMS settings

Background

We investigated paramedic-initiated consultation calls and advice given via telephone by Helicopter Emergency Medical Service (HEMS) physicians focusing on limitations of medical treatment (LOMT).

Methods

A prospective multicentre study was conducted on four physician-staffed HEMS bases in Finland during a 6-month period.

Results

Of all 6115 (mean 8.4/base/day) paramedic-initiated consultation calls, 478 (7.8%) consultation calls involving LOMTs were included: 268 (4.4%) cases with a pre-existing LOMT, 165 (2.7%) cases where the HEMS physician issued a new LOMT and 45 (0.7%) cases where the patient already had an LOMT and the physician further issued another LOMT. The most common new limitation was a do-not-attempt cardiopulmonary resuscitation (DNACPR) order (n = 122/210, 58%) and/or ‘not eligible for intensive care’ (n = 96/210, 46%). In 49 (23%) calls involving a new LOMT, termination of an initiated resuscitation attempt was the only newly issued LOMT. The most frequent reasons for issuing an LOMT during consultations were futility of the overall situation (71%), poor baseline functional status (56%), multiple/severe comorbidities (56%) and old age (49%). In the majority of cases (65%) in which the HEMS physician issued a new LOMT for a patient without any pre-existing LOMT, the physician felt that the patient should have already had an LOMT. The patient was in a health care facility or a nursing home in half (49%) of the calls that involved issuing a new LOMT. Access to medical records was reported in 29% of the calls in which a new LOMT was issued by an HEMS physician.

Conclusion

Consultation calls with HEMS physicians involving patients with LOMT decisions were common. HEMS physicians considered end-of-life questions on the phone and issued a new LOMT in 3.4% of consultations calls. These decisions mainly concerned termination of resuscitation, DNACPR, intubation and initiation of intensive care.

Ambulance clinicians' attitudes to older patients' self-determination when the patient has impaired decision-making ability: A Delphi study

OBJECTIVE

The proportion of older people is increasing and reflects in the demand on ambulance services (AS). Patients can be more vulnerable and increasingly dependent, especially when their decision-making ability is impaired. Self-determination in older people has a positive relation to quality of life and can raise ethical conflicts in AS. Hence, the aim of this study was to empirically explore attitudes among Swedish ambulance clinicians (ACs) regarding older patients' self-determination in cases where patients have impaired decision-making ability, and who are in urgent need of care.

MATERIALS AND METHODS

An explorative design was adopted. A Delphi technique was used, comprising four rounds, involving a group (N = 31) of prehospital emergency nurses (n = 14), registered nurses (n = 10) and emergency medical technicians (n = 7). Focus group conversations (Round 1) and questionnaires (Rounds 2-4) generated data. Round 1 was analysed using manifest content analysis, which ultimately resulted in the creation of discrete items. Each item was rated with a five-point Likert scale together with free-text answers. Consensus (≥70%) was calculated by trichotomising the Likert scale.

RESULTS

Round 1 identified 108 items which were divided into four categories: (1) attitudes regarding the patient (n = 35), (2) attitudes regarding the patient relationship (n = 8), (3) attitudes regarding oneself and one's colleagues (n = 45), and (4) attitudes regarding other involved factors (n = 20). In Rounds 2-4, one item was identified in the free text from Round 2, generating a total of 109 items. After four rounds, 72 items (62%) reached consensus.

CONCLUSIONS

The findings highlight the complexity of ACs' attitudes towards older patients' self-determination. The respect of older patients' self-determination is challenged by the patient, other healthcare personnel, significant others and/or colleagues. The study provided a unique opportunity to explore self-determination and shared decision-making. AS have to provide continued ethical training, for example to increase the use of simulation-based training or moral case deliberations in order to strengthen the ACs' moral abilities within their professional practice.

IMPLICATIONS FOR PRACTICE

Ambulance services must develop opportunities to provide continued training within this topic. One option would be to increase the use of simulation-based training, focusing on ethical aspects of the care. Another option might be to facilitate moral case deliberations to strengthen the ACs' abilities to manage these issues while being able to share experiences with peers. These types of interventions should illuminate the importance of the topic for the individual AC, which, in turn, may strengthen and develop the caring abilities within an integrated care team.

Factors Influencing Physician Decision Making to Attempt Advanced Resuscitation in Asystolic Out-of-Hospital Cardiac Arrest

The objective of this study was to identify the key elements used by prehospital emergency physicians (EP) to decide whether or not to attempt advanced life support (ALS) in asystolic out-of-hospital cardiac arrest (OHCA). From 1 January 2009 to 1 January 2017, all adult victims of asystolic OHCA in Geneva, Switzerland, were retrospectively included. Patients with signs of “obvious death” or with a Do-Not-Attempt-Resuscitation order were excluded. Patients were categorized as having received ALS if this was mentioned in the medical record, or, failing that, if at least one dose of adrenaline had been administered during cardiopulmonary resuscitation (CPR). Prognostic factors known at the time of EP’s decision were included in a multivariable logistic regression model. Included were 784 patients. Factors favourably influencing the decision to provide ALS were witnessed OHCA (OR = 2.14, 95% CI: 1.43–3.20) and bystander CPR (OR = 4.10, 95% CI: 2.28–7.39). Traumatic aetiology (OR = 0.04, 95% CI: 0.02–0.08), age > 80 years (OR = 0.14, 95% CI: 0.09–0.24) and a Charlson comorbidity index greater than 5 (OR = 0.12, 95% CI: 0.06–0.27) were the factors most strongly associated with the decision not to attempt ALS. Factors influencing the EP’s decision to attempt ALS in asystolic OHCA are the relatively young age of the patients, few comorbidities, presumed medical aetiology, witnessed OHCA and bystander CPR.

South African paramedic perspectives on prehospital palliative care

Background

Palliative care is typically performed in-hospital. However, Emergency Medical Service (EMS) providers are uniquely positioned to deliver early palliative care as they are often the first point of medical contact. The aim of this study was to gather the perspectives of advanced life support (ALS) providers within the South African private EMS sector regarding pre-hospital palliative care in terms of its importance, feasibility and barriers to its practice.

Methods

A qualitative study design employing semi-structured one-on-one interviews was used. Six interviews with experienced, higher education qualified, South African ALS providers were conducted. Content analysis, with an inductive-dominant approach, was performed to identify categories within verbatim transcripts of the interview audio-recordings.

Results

Four categories arose from analysis of six interviews: 1) need for pre-hospital palliative care, 2) function of pre-hospital healthcare providers concerning palliative care, 3) challenges to pre-hospital palliative care and 4) ideas for implementing pre-hospital palliative care. According to the interviewees of this study, pre-hospital palliative care in South Africa is needed and EMS providers can play a valuable role, however, many challenges such as a lack of education and EMS system and mindset barriers exist.

Conclusion

Challenges to pre-hospital palliative care may be overcome by development of guidelines, training, and a multi-disciplinary approach to pre-hospital palliative care.

Limiting treatment in pre-hospital care: A prospective, observational multicentre study

BACKGROUND

Data are scarce on the withdrawal of life-sustaining therapies and limitation of care orders (LCOs) during physician-staffed Helicopter Emergency Medical Service (HEMS) missions. We investigated LCOs and the quality of information available when physicians made treatment decisions in pre-hospital care.

METHODS

A prospective, nationwide, multicentre study including all Finnish physician-staffed HEMS bases during a 6-month study period. All HEMS missions where a patient had pre-existing LCOs and/or a new LCO were included.

RESULTS

There were 335 missions with LCOs, which represented 5.7% of all HEMS missions (n = 5895). There were 181 missions with pre-existing LCOs, and a total of 170 new LCOs were issued. Usually, the pre-existing LCO was a do not attempt cardiopulmonary resuscitation order only (n = 133, 74%). The most frequent new LCO was 'termination of cardiopulmonary resuscitation' only (n = 61, 36%), while 'no intensive care' combined with some other LCO was almost as common (n = 54, 32%). When issuing a new LCO for patients who did not have any preceding LCOs (n = 153), in every other (49%) case the physicians thought that the patient should have already had an LCO. When the physician made treatment decisions, patients' background information from on-scene paramedics was available in 260 (78%) of the LCO missions, while patients' medical records were available in 67 (20%) of the missions.

CONCLUSION

Making LCOs or treating patients with pre-existing LCOs is an integral part of HEMS physicians' work, with every twentieth mission involving LCO patients. The new LCOs mostly concerned withholding or withdrawal of cardiopulmonary resuscitation and intensive care.

Limitation of treatment in prehospital care - the experiences of helicopter emergency medical service physicians in a nationwide multicentre survey

Background

Making ethically sound treatment limitations in prehospital care is a complex topic. Helicopter Emergency Medical Service (HEMS) physicians were surveyed on their experiences with limitations of care orders in the prehospital setting, including situations where they are dispatched to healthcare facilities or nursing homes.

Methods

A nationwide multicentre study was conducted among all HEMS physicians in Finland in 2017 using a questionnaire with closed five-point Likert-scale questions and open questions. The Ethics Committee of the Tampere University Hospital approved the study protocol (R15048).

Results

Fifty-nine (88%) physicians responded. Their median age was 43 (IQR 38–47) and median medical working experience was 15 (IQR 10–20) years. All respondents made limitation of care orders and 39% made them often. Three fourths (75%) of the physicians were often dispatched to healthcare facilities and nursing homes and the majority (93%) regularly met patients who should have already had a valid limitation of care order. Every other physician (49%) had sometimes decided not to implement a medically justifiable limitation of care order because they wanted to avoid conflicts with the patient and/or the next of kin and/or other healthcare staff. Limitation of care order practices varied between the respondents, but neither age nor working experience explained these differences in answers. Most physicians (85%) stated that limitations of care orders are part of their work and 81% did not find them especially burdensome. The most challenging patient groups for treatment limitations were the under-aged patients, the severely disabled patients and the patients in healthcare facilities or residing in nursing homes.

Conclusion

Making limitation of care orders is an important but often invisible part of a HEMS physician’s work. HEMS physicians expressed that patients in long-term care were often without limitations of care orders in situations where an order would have been ethically in accordance with the patient’s best interests.

Withholding and withdrawing life-support in adults in emergency care: joint position paper from the French Intensive Care Society and French Society of Emergency Medicine

For many patients, notably among elderly nursing home residents, no plans about end-of-life decisions and palliative care are made. Consequently, when these patients experience life-threatening events, decisions to withhold or withdraw life-support raise major challenges for emergency healthcare professionals. Emergency department premises are not designed for providing the psychological and technical components of end-of-life care. The continuous inflow of large numbers of patients leaves little time for detailed assessments, and emergency department staff often lack training in end-of-life issues. For prehospital medical teams (in France, the physician-staffed mobile emergency and intensive care units known as SMURs), implementing treatment withholding and withdrawal decisions that may have been made before the acute event is not the main focus. The challenge lies in circumventing the apparent contradiction between the need to make immediate decisions and the requirement to set up a complex treatment project that may lead to treatment withholding and/or withdrawal. Laws and recommendations are of little assistance for making treatment withholding and withdrawal decisions in the emergency setting. The French Intensive Care Society (Société de Réanimation de Langue Française, SRLF) and French Society of Emergency Medicine (Société Française de Médecine d'Urgence, SFMU) tasked a panel of emergency physicians and intensivists with developing a document to serve both as a position paper on life-support withholding and withdrawal in the emergency setting and as a guide for professionals providing emergency care. The task force based its work on the available legislation and recommendations and on a review of published studies.

Décès et limitations thérapeutiques aux urgences : étude rétrospective des pratiques dans un centre hospitalier français pendant quatre ans

Objectifs : Nous avons analysé les caractéristiques médicoadministratives et la prise en charge des patients décédés dans le service d’accueil des urgences (SAU) d’un centre hospitalier français.

Matériels et méthodes : Il s’agissait d’une étude rétrospective observationnelle des patients décédés aux urgences entre janvier 2012 et décembre 2015. Nous avons analysé les procédures de limitation et d’arrêt des thérapeutiques actives (LATA) et comparé les caractéristiques des groupes de patients « LATA » et « Non LATA ».

Résultats : Deux cent trente-deux patients sont décédés au SAU en quatre ans. Vingt pour cent des décès sont survenus très rapidement malgré les soins de réanimation, et 80 % sont survenus après une décision de LATA. Les LATA étaient décidées par un urgentiste seul dans 56 % des cas et avec un délai de réflexion très court : 13 % en préhospitalier et 28 % au cours de la première heure au SAU. Quatorze pour cent des LATA n’étaient pas inscrites dans le dossier médical. Les patients en LATA étaient plus âgés, plus souvent déments, venaient de maison de retraite et étaient adressés pour des motifs plus graves (p < 0,01). Ils ont généralement bénéficié de soins de confort en unité d’hospitalisation de courte durée : antalgiques, hypnotiques et antisécrétoires lorsque cela était nécessaire.

Conclusion : Deux tiers des procédures de LATA ne respectaient pas les recommandations de bonne pratique en termes de collégialité et de traçabilité. Une amélioration des pratiques est possible au SAU par l’élaboration d’une nouvelle procédure de LATA prenant en compte les contraintes de l’urgence.

Évaluation des prises de décisions de limitations et d’arrêt des thérapeutiques chez les patients décédés aux urgences

Introduction : Les décisions de limitation et arrêt des thérapeutiques (LAT) sont encadrées par la loi du 22 avril 2005 relative aux droits des malades et à la fin de vie. Au lendemain de sa révision, le 2 février 2016, cette situation reste toujours aussi complexe aux urgences. Notre travail avait pour but d’évaluer la prise de décision des limitations de soins aux urgences.

Matériel et méthode : Il s’agissait d’une étude rétrospective, observationnelle, monocentrique. Le recueil des données a été fait par une relecture des dossiers concernant les patients décédés entre le 1er janvier 2014 et le 5 mai 2015. L’objectif de notre travail était de décrire les modalités de prise de décision de limitations de soins, ainsi que leur adéquation avec la loi.

Résultats : Nous avions inclus 91 dossiers de patients décédés. Parmi les 58 dossiers (64%) où l’autonomie était retrouvée, elle était très limitée chez 50 patients (Knaus C + D), soit 86%. La décision était inscrite dans 74 dossiers (81%), mais détaillée dans 40 seulement (44%). Soixante-quinze fois (83%), la famille a été informée. Dans 70 (80%) des 87 situations où les intervenants étaient identifiés, la procédure collégiale était respectée. Une thérapeutique palliative a été initiée chez 67 des défunts (74%).

Conclusion : Les décisions de LAT sont encore perfectibles aux urgences pour être en adéquation avec la loi. Des améliorations sont possibles en intégrant des programmes de formations du personnel et des protocoles éthiques d’aide à la décision.

Surveying End-of-Life Medical Decisions in France: Evaluation of an Innovative Mixed-Mode Data Collection Strategy

Background

Monitoring medical decisions at the end of life has become an important issue in many societies. Built on previous European experiences, the survey and project Fin de Vie en France (“End of Life in France,” or EOLF) was conducted in 2010 to provide an overview of medical end-of-life decisions in France.

Objective

To describe the methodology of EOLF and evaluate the effects of design innovations on data quality.

Methods

EOLF used a mixed-mode data collection strategy (paper and Internet) along with follow-up campaigns that employed various contact modes (paper and telephone), all of which were gathered from various institutions (research team, hospital, and medical authorities at the regional level). A telephone nonresponse survey was also used. Through descriptive statistics and multivariate logistic regressions, these innovations were assessed in terms of their effects on the response rate, quality of the sample, and differences between Web-based and paper questionnaires.

Results

The participation rate was 40.0% (n=5217). The respondent sample was very close to the sampling frame. The Web-based questionnaires represented only 26.8% of the questionnaires, and the Web-based secured procedure led to limitations in data management. The follow-up campaigns had a strong effect on participation, especially for paper questionnaires. With higher participation rates (63.21% and 63.74%), the telephone follow-up and nonresponse surveys showed that only a very low proportion of physicians refused to participate because of the topic or the absence of financial incentive. A multivariate analysis showed that physicians who answered on the Internet reported less medication to hasten death, and that they more often took no medical decisions in the end-of-life process.

Conclusions

Varying contact modes is a useful strategy. Using a mixed-mode design is interesting, but selection and measurement effects must be studied further in this sensitive field.

[Palliative care at home, transferring information to emergency medical teams]

Many people wish to die at home. However, the end-of-life period can be marked by the occurrence of numerous symptoms causing situations of crisis. Emergency medical teams are therefore frequently called upon. In order to be able to make the right decisions in a short space of time, they must have quick access to all the relevant information.

Ethical values in emergency medical services: A pilot study

BACKGROUND

Ambulance professionals often address conflicts between ethical values. As individuals' values represent basic convictions of what is right or good and motivate behaviour, research is needed to understand their value profiles.

OBJECTIVES

To translate and adapt the Managerial Values Profile to Spanish and Swedish, and measure the presence of utilitarianism, moral rights and/or social justice in ambulance professionals' value profiles in Spain and Sweden.

METHODS

The instrument was translated and culturally adapted. A content validity index was calculated. Pilot tests were carried out with 46 participants.

ETHICAL CONSIDERATIONS

This study conforms to the ethical principles for research involving human subjects and adheres to national laws and regulations concerning informed consent and confidentiality.

FINDINGS

Spanish professionals favoured justice and Swedish professionals' rights in their ambulance organizations. Both countries favoured utilitarianism least. Gender differences across countries showed that males favoured rights. Spanish female professionals favoured justice most strongly of all.

DISCUSSION

Swedes favour rights while Spaniards favour justice. Both contexts scored low on utilitarianism focusing on total population effect, preferring the opposite, individualized approach of the rights and justice perspectives. Organizational investment in a utilitarian perspective might jeopardize ambulance professionals' moral right to make individual assessments based on the needs of the patient at hand. Utilitarianism and a caring ethos appear as stark opposites. However, a caring ethos in its turn might well involve unreasonable demands on the individual carer's professional role. Since both the justice and rights perspectives portrayed in the survey mainly concern relationship to the organization and peers within the organization, this relationship might at worst be given priority over the equal treatment and moral rights of the patient.

CONCLUSION

A balanced view on ethical perspectives is needed to make professionals observant and ready to act optimally - especially if these perspectives are used in patient care. Research is needed to clarify how justice and rights are prioritized by ambulance services and whether or not these organization-related values are also implemented in patient care.

End-of-life medical decisions in France: a death certificate follow-up survey 5 years after the 2005 act of parliament on patients' rights and end of life

Background

The “Patients’ Rights and End of Life Care” Act came into force in France in 2005. It allows withholding/withdrawal of life-support treatment, and intensified use of medications that may hasten death through a double effect, as long as hastening death is not the purpose of the decision. It also specifies the requirements of the decision-making process. This study assesses the situation by examining the frequency of end-of-life decisions by patients’ and physicians’ characteristics, and describes the decision-making processes.

Methods

We conducted a nationwide retrospective study of a random sample of adult patients who died in December 2009. Questionnaires were mailed to the physicians who certified/attended these deaths. Cases were weighted to adjust for response rate bias. Bivariate analyses and logistic regressions were performed for each decision.

Results

Of all deaths, 16.9% were sudden deaths with no information about end of life, 12.2% followed a decision to do everything possible to prolong life, and 47.7% followed at least one medical decision that may certainly or probably hasten death: withholding (14.6%) or withdrawal (4.2%) of treatments, intensified use of opioids and/or benzodiazepines (28.1%), use of medications to deliberately hasten death (i.e. not legally authorized) (0.8%), at the patient’s request (0.2%) or not (0.6%). All other variables held constant, cause of death, patient's age, doctor’s age and specialty, and place of death, influenced the frequencies of decisions. When a decision was made, 20% of the persons concerned were considered to be competent. The decision was discussed with the patient if competent in 40% (everything done) to 86% (intensification of alleviation of symptoms) of cases. Legal requirements regarding decision-making for incompetent patients were frequently not complied with.

Conclusions

This study shows that end-of-life medical decisions are common in France. Most are in compliance with the 2005 law (similar to some other European countries). Nonetheless, the study revealed cases where not all legal obligations were met or where the decision was totally illegal. There is still a lot to be done through medical education and population awareness-raising to ensure that the decision-making process is compatible with current legislation, the physician's duty of care and the patient’s rights.

[The law number 2005-370 of April 22, 2005 concerning the patients' rights at the end-of-life: improvement of the withholding and withdrawing treatment decision-making process by an educational program. A monocenter prospective and retrospective pilot study]

OBJECTIVE

To assess the impact of an educational program on the quality of the end-of-life decision (EOLD).

METHODS

Prospective study for 3 months in a surgical Intensive Care Unit (ICU) involving: staff training conferences and guidelines for documenting level-of-care staff conference; audit before and at 3 months; analysis of records for deceased patients. The main outcome measures the proportion of treatment-limitation in dying ICU patients; and the secondary outcomes the decision-making process and nurses' satisfaction.

RESULTS

Eighty-three patients were included; among them, 14 with EOLD. Pre-death palliative strategy increased from 51 % to 85 % with a persisting improvement of practices after 2 years. All steps of EOLD decision-making processes were traced in all such cases, 85 % being based on the proposed guidelines. Nursing team's satisfaction rate almost doubled to 70 %.

DISCUSSION

The study demonstrate staff members' capacity to quickly improve their procedures for palliative care when provided with appropriate tools to think about the process and come to a decision. Our data suggest the potential benefice to extend this program to the other specialties involved in the end-of-life process.

Prehospital noninvasive ventilation can help in management of patients with limitations of life-sustaining treatments

OBJECTIVE

To evaluate the possible place of noninvasive positive pressure ventilation (NPPV) as a reversible and adjustable option offering the possibility of sustaining life until the hospital stay for patients with advanced life-support limitations and life-threatening respiratory distress in the prehospital setting.

METHODS

Patients managed by a physician-staffed Emergency Medical Service unit were retrospectively included if they met the three inclusion criteria: a respiratory failure with oxygen saturation (pulse oximetry) less than 90% (or respiratory exhaustion) under oxygen 15 l/min and a do-not-intubate discussion (according to the physician on-scene) and impossibility of conducting the discussion of withholding advanced life support on-scene.

RESULTS

Twelve patients were included. NPPV was a continuous positive airway pressure for eight patients and a bilevel positive airway pressure given by a ventilator for four patients. All the patients improved from respiratory point of view; respiratory rate decreased from 34 + or - 13 to 27 + or - 10 (P = 0.009) and pulse oximetry increased from 86 + or - 5 to 94 + or - 3% (P<0.01). NPPV was stopped in one case because of discomfort and worsening of consciousness, despite improved respiratory status.

CONCLUSION

This pilot series is promising and suggests that it could be a good option in case of limitations of life-sustaining treatments in the prehospital setting. A large controlled multicenter study, evaluating the use of NPPV in this context, would be very valuable.

Withholding advanced cardiac life support in out-of-hospital cardiac arrest: A prospective study

AIM OF THE STUDY

To evaluate the decision criteria leading to refrain from starting cardiopulmonary resuscitation (CPR) in the prehospital setting.

MATERIALS AND METHODS

We conducted a prospective, descriptive study, in a physician-staffed emergency medical service during a 12 month period. All patients presenting with a cardiac arrest were included. Patients were allocated to two groups: immediate decision to give CPR (R group) or withholding CPR (NR group). Characteristics of patients including previous health status, time intervals, therapies and outcomes, were collected. Data were compared between the two groups, *p<0.05.

RESULTS

One hundred and fourteen patients (aged 61+/-18 years) were enrolled in R group and 113 (73+/-19 years*) in NR group. Patients of NR group more frequently presented with a deterioration of functional independence (51% versus 10%*), cognitive impairment (21% versus 8%*) and higher McCabe score and Knaus class (McCabe 2: 24% versus 2%*; Knaus class D: 23% versus 3%*). Presence of a bystander (75% versus 44%*) or basic life support (BLS) started by the bystander (40% versus 12%*) were more frequent in R than NR. Age (OR, 1.1; 95% CI, 1.0-1.1), McCabe score >0 (OR, 10.5; 95% CI, 1.4-79.0), lack of bystander BLS (OR, 11.2; 95% CI, 2.2-60.7) and ineffectiveness of BLS by EMTs (OR, 12.1; 95% CI, 2.0-72.8) were independent factors of withholding CPR. The physician conducted often the discussion alone (48%).

CONCLUSION

Decision criteria leading to refrain from starting CPR in the prehospital setting are age, previous health status and initial BLS. Further thought should be allowed to ensure a share in the decision-making process in this particular practice.
