The value of uncertainty in critical illness? An ethnographic study of patterns and conflicts in care and decision-making trajectories

Abstract

BackgroundWith increasingly intensive treatments and population ageing, more people face complex treatment and care decisions. We explored patterns of the decision-making processes during critical care, and sources of conflict and resolution.MethodsEthnographic study in two Intensive Care Units (ICUs) in an inner city hospital comprising: non-participant observation of general care and decisions, followed by case studies where treatment limitation decisions, comfort care and/or end of life discussions were occurring. These involved: semi-structured interviews with consenting families, where possible, patients; direct observations of care; and review of medical records.ResultsInitial non-participant observation included daytime, evenings, nights and weekends. The cases were 16 patients with varied diagnoses, aged 19-87 years; 19 family members were interviewed, aged 30-73 years. Cases were observed for <1 to 156 days (median 22), depending on length of ICU admission. Decisions were made serially over the whole trajectory, usually several days or weeks. We identified four trajectories with distinct patterns: curative care from admission; oscillating curative and comfort care; shift to comfort care; comfort care from admission. Some families considered decision-making a negative concept and preferred uncertainty. Conflict occurred most commonly in the trajectories with oscillating curative and comfort care. Conflict also occurred inside clinical teams. Families were most often involved in decision-making regarding care outcomes and seemed to find it easier when patients switched definitively from curative to comfort care. We found eight categories of decision-making; three related to the care outcomes (aim, place, response to needs) and five to the care processes (resuscitation, decision support, medications/fluids, monitoring/interventions, other specialty involvement).ConclusionsDecision-making in critical illness involves a web of discussions regarding the potential outcomes and processes of care, across the whole disease trajectory. When measures oscillate between curative and comfort there is greatest conflict. This suggests a need to support early communication, especially around values and preferred care outcomes, from which other decisions follow, including DNAR. Offering further support, possibly with expert palliative care, communication, and discussion of ‘trial of treatment’ may be beneficial at this time, rather than waiting until the ‘end of life’.

The state of bereavement support in adult intensive care: A systematic review and narrative synthesis

“…Death and dying in ICU may be similar to other contexts, but this depends on the trajectory of death itself. Dying trajectories in ICU include: sudden death; acute illness or injury with rapid deterioration; chronic illness with gradual decline leading to withdrawal of treatment, and prolonged deterioration with patients moving in and out of serious illness [6,7,8]. Due to the unpredictable dying trajectories, the nature of critical illness and advanced technical care in ICU which aims at curing, the emotional preparation of the family for the possibility of patient death may be overlooked [9,10].…”

Identifying Information Resources for Patients in the Intensive Care Unit and Their Families

“…4,5 Patients in the ICU and their families have varying abilities and willingness to participate in care and decision-making. 6 Patient education requires a flexible approach, especially with family members who become the main points of contact for decision-making on behalf of the patients. 7,8 Family members of critically ill patients consistently identify the need for information and the need for reassurance as the highest priority needs during an ICU hospitalization, yet the need for information is often unmet.…”

Problematiche di fine vita: il ruolo della medicina interna ospedaliera

“…105 Le informazioni prognostiche sono un elemento fondante nell'assistenza, richieste dai pazienti e dalle loro famiglie, ma necessarie anche per lo staff assistenziale e tutti gli operatori sanitari; le previsioni di sopravvivenza effettuate dai clinici e dagli infermieri sono il fondamento della pratica corrente, ma purtroppo, in quanto soggettive e a volte troppo ottimistiche, non sono sempre affidabili. Il percorso decisionale in condizioni d'incertezza è sempre problematico 106 e non esiste ancora uno strumento definitivo di screening per identificare, anche in termini temporali, i pazienti che sono a rischio di obitus. Un attento giudizio prognostico è particolarmente importante per il processo decisionale nei pazienti più anziani.…”
