The Critical Care Society of Southern Africa Consensus Statement on ICU Triage and Rationing (ConICTri).

Background. In South Africa (SA), intensive care is faced with the challenge of resource scarcity as well as an increasing demand for intensive care unit (ICU) services. ICU services are expensive, and practitioners in low- to middle-income countries experience daily the consequences of limited resources. Critically limited resources necessitate that rationing and triage (prioritisation) decisions are frequently necessary in SA, particularly in the publicly funded health sector. Purpose. The purpose of this consensus statement is to examine key questions that arise when considering the status of ICU resources in SA, and more specifically ICU admission, rationing and triage decisions. The accompanying guideline in this issue is intended to guide frontline triage policy and ensure the best utilisation of intensive care in SA, while maintaining a fair distribution of available resources. Fair and efficient triage is important to ensure the ongoing provision of high-quality care to adult patients referred for intensive care. Recommendations. In response to 14 key questions developed using a modified Delphi technique, 29 recommendations were formulated and graded using an adapted GRADE score. The 14 key questions addressed the status of the provision of ICU services in SA, the degree of resource restriction, the efficiency of resource management, the need for triage, and how triage could be most justly implemented. Important recommendations included the need to formally recognise and accurately quantify the provision of ICU services in SA by national audit; actively seek additional resources from governmental bodies; consider methods to maximise the efficiency of ICU care; evaluate lower level of care alternatives; develop a triage guideline to assist policy-makers and frontline practitioners to implement triage decisions in an efficient and fair way; measure and audit the consequence of triage; and promote research to improve the accuracy and consistency of triage decisions. The consensus document and guideline should be reviewed and revised appropriately within 5 years. Conclusion. In recognition of the absolute need to limit patient access to ICU because of the lack of sufficient intensive care resources in public hospitals, recommendations and a guideline have been developed to guide policy-making and assist frontline triage decision-making in SA. These documents are not a complete plan for quality practice but rather the beginning of a long-term initiative to engage clinicians, the public and administrators in appropriate triage decision-making, and promote systems that will ultimately maximise the efficient and fair use of available ICU resources.

The Critical Care Society of Southern Africa Consensus Guideline on ICU Triage and Rationing (ConICTri).

Background. In South Africa (SA), administrators and intensive care practitioners are faced with the challenge of resource scarcity as well as an increasing demand for intensive care unit (ICU) services. ICU services are expensive, and practitioners in low- to middle-income countries experience the consequences of limited resources daily. Critically limited resources necessitate that rationing and triage (prioritisation) decisions are routinely necessary in SA, particularly in the publicly funded health sector. Purpose. The purpose of this guideline is to utilise the relevant recommendations of the associated consensus meeting document and other internationally accepted principles to develop a guideline to inform frontline triage policy and ensure the best utilisation of adult intensive care in SA, while maintaining the fair distribution of available resources. Recommendations. An overall conceptual framework for the triage process was developed. The components of the framework were developed on the basis that patients should be admitted preferentially when the likely incremental medical benefit derived from ICU admission justifies admission. An estimate of likely resource use should also form part of the triage decision, with those patients requiring relatively less resources to achieve substantial benefit receiving priority for admission. Thus, the triage system should maximise the benefits obtained from ICU resources available for the community. Where possible, practical examples of what the consensus group agreed would be considered appropriate practice under specified South African circumstances were provided, to assist clinicians with practical decision-making. It must be stressed that this guideline is not intended to be prescriptive for individual hospital or regional practice, and hospitals and regions are encouraged to develop specified local guidelines with locally relevant examples. The guideline should be reviewed and revised if appropriate within 5 years. Conclusion. In recognition of the absolute need to limit patient access to ICU because of the lack of sufficient intensive care resources in public hospitals, this guideline has been developed to guide policy-making and assist frontline triage decision-making in SA. This document is not a complete plan for quality practice, but rather a template to support frontline clinicians, guide administrators and inform the public regarding appropriate triage decision-making.

Cost awareness among healthcare professionals at a South African hospital: A cross-sectional survey.

BACKGROUND: Financial cost is a recognised cause of lack of access to adequate healthcare in South Africa (SA). Data describing the SA healthcare professional (HCP)'s awareness of costs are scant. Their increased awareness of healthcare costs may improve efficacy and reduce wasteful expenditure. OBJECTIVE: To assess SA HCP's knowledge of healthcare costs, identify factors that influence cost awareness, and to determine if surveyed HCPs received training related to cost management during their studies or at any stage during their practice. METHODS: This cross-sectional survey was conducted by means of a standardised questionnaire. HCPs working at a major tertiary academic hospital were asked to answer an anonymous standardised questionnaire aimed at determining their awareness of the costs of commonly requested hospital items and tests. Cost accuracy was determined by assessing the log deviation of the estimated cost from true cost, with values >0 and <0 representing overestimates and underestimates, respectively. Cost estimations were considered correct if the absolute value of the log deviation was <0.2. Participants' attitudes towards the potential impact of the availability of cost information on their practice were assessed. RESULTS: The overall cost estimation of accuracy was low (mean 0.60; standard deviation 1.99) and differed widely between items. Cheaper items were more likely to be overestimated and expensive items to be underestimated. The majority of participants indicated that cost awareness education was not part of their training or practice (84.5%) and that they would like cost information to be made readily available (92.2%). Eighty-four percent of participants were of the opinion that cost information would not negatively affect patient care. CONCLUSION: The use of percentage deviation from true cost as a method of assessing cost awareness creates a bias towards overestimation, which is more relevant for cheap items, as larger overestimates are more common for these items. We propose the use of log deviation of the estimated cost from the true cost as a method of assessing cost estimation accuracy. HCPs have a limited understanding of the costs of disposables, tests and drugs commonly used in their practice and would prefer that cost information be made readily available to them. Attention should be paid to improving cost awareness among HCPs working at SA hospitals.

Ciprofloxacin pharmacokinetic profiles in paediatric sepsis: how much ciprofloxacin is enough?

OBJECTIVE: To determine the pharmacokinetic profile of ciprofloxacin 20 mg/kg per day (10 mg/kg administered intravenously 12 hourly) in paediatric patients with severe sepsis. DESIGN: Open and prospective. SETTING: Tertiary referral multi-disciplinary ICU. PATIENTS: Twenty patients (two groups - group A: 3 months-1 year; group B 1-5 years). INTERVENTIONS: Timed blood samples were taken for pharmacokinetics after the first dose (D(0)), as well as day 2 (D(2)) and then between days 6-8. MEASUREMENTS AND RESULTS: Ciprofloxacin serum levels were measured by high performance liquid chromatography. Demographic and clinical data and all adverse events were noted. Standard pharmacokinetic variables were calculated by non-compartmental methods. Peak concentrations (C(max)) for group A were D(0) 6.1+/-1.2 mg/l, D(2) 9.0+/-1.8 mg/l and D(7) 5.8+/-1.3 mg/l and, for group B, 7.4+/-1.3 mg/l, 7.8+/-1.6 mg/l and 6.4+/-1.3 mg/l, respectively, for the study periods. Concentration 12 h after the start of infusion (C(min)) for all periods were 0.2 mg/l or less. Areas under the curve (AUC, 12 h) were group A: 15.6+/-1.3, 19.2+/-1.63 and 14.1+/-1.4 mg/h per l, and group B: 15.9+/-1.3, 18.0+/-1.7 and 13.2+/-1.26 mg/h per l. One patient presenting with seizures, initially controlled, had another convulsion and a further patient developed seizures whilst on ciprofloxacin. C(max) in these patients were higher than the average C(max). The convulsions of both patients were easily controlled. No other drug-related serious adverse events occurred. No arthropathy was noted. Three patients died of their underlying disease. CONCLUSIONS: There was no accumulation of drug even after 7 days of administration. Our C(max) and AUC were lower than that achieved in a similar adult pharmacokinetic study. To achieve end points of area under the inhibitory curve (AUIC) of 100-150 mg/h per l, 10 mg/kg ciprofloxacin eight hourly would be required for some resistant ICU organisms.

Pharmacokinetic profiles of high-dose intravenous ciprofloxacin in severe sepsis. The Baragwanath Ciprofloxacin Study Group.

The pharmacokinetics of 400 mg of ciprofloxacin given intravenously (i.v.) every 8 h (q8h) in severely septic adults was documented in a multidisciplinary, tertiary referral intensive care unit (ICU). Sixteen evaluable patients (three pharmacokinetic profiles) without renal dysfunction and with severe sepsis were studied. Ciprofloxacin at a dosage of 400 mg given i.v. q8h was administered over 1 h. Plasma samples for assay (high-pressure liquid chromatography) were taken at timed intervals (preinfusion, at the end of infusion, and at 1, 2, 3, 5, and 7 h postinfusion) for first-dose kinetics (day 0 [D0]), D2, and between D6 and D8. All pharmacokinetic variables were calculated by noncompartmental methods. Standard intensive care was provided. Peak ciprofloxacin concentrations were as follows: D0, 6. 01 +/- 1.93 mg/liter; D2, 6.68 +/- 2.01 mg/liter; and D6 to D8 6.45 +/- 1.54 mg/liter. Trough levels were as follows: D0, 0.6 +/- 0.5 mg/liter; D2, 0.7 +/- 0.4 mg/liter; and D6 to D8 0.6 +/- 0.4 mg/liter. The areas under the concentration curves (8 h) were as follows: D0, 13.3 +/- 3.8 mg . h/liter; D2, 16.8 +/- 5.4 mg . h/liter; and D6 to D8, 15.5 +/- 4.7 mg . h/liter. No drug-related serious adverse events occurred. For 17 of 18 patients enrolled in the study, the causative organisms were susceptible to ciprofloxacin. One patient developed renal failure (non-drug related) after the administration of three doses of ciprofloxacin. One patient was infected with ciprofloxacin-resistant organisms on enrollment. Nine of 16 evaluable patients had clinical cures, and 8 had bacteriological cures. One patient developed a ciprofloxacin-resistant superinfection. In two patients the clinical course was indeterminate. Two bacteriological failures occurred. We conclude that in critically ill adults ciprofloxacin at a dosage of 400 mg given i.v. q8h is safe. Its pharmacokinetic profile provides bactericidal activity against most organisms encountered in an ICU. Except for some initial accumulation on D2, no further accumulation occurred in patients without renal failure. Ciprofloxacin should be administered i.v. at a dosage of 400 mg q8h for severe sepsis.

Critical care research and pre-emptive informed consent: a practical approach used in Chris Hani Baragwanath ICU.

OBJECTIVES: 1) To establish a protocol within international and local ethical guidelines to obtain informed consent for critical care research, overcoming constraints previously described and 2) To evaluate eventual recruitment using this protocol. DESIGN: Prospective descriptive study. SETTING: Multidisciplinary ICU in a community-based university teaching hospital. PATIENTS AND PARTICIPANTS: Following approval by the University Ethics Committee and Hospital Review Board, patients admitted between January and May 1996 were assessed on weekdays for potential enrollment into existing clinical trials. Discussion with potential candidates and/or next-of-kin occurred at the earliest opportunity and informed consent was obtained preemptively. Next-of-kin was notified if enrollment subsequently occurred. We evaluated the number of patients screened, the number of potential study candidates, the number for whom consent was obtained or refused and the number subsequently enrolled. INTERVENTIONS: None RESULTS: Of 249 patients screened, 149 (60%) did not meet the inclusion criteria. Of 100 potential study candidates (40% of all patients screened), we failed to make contact with the next-of-kin in 29 cases (12% of all patients screened). Thus 71 patients or next-of-kin were counselled (28% of all patients screened). In all, 30 patients (12% of all patients screened) were subsequently enrolled into a study. CONCLUSIONS: A policy of pre-emptive informed consent enabled us to overcome some of the problems previously experienced in our unit with regards to patient enrollment in critical care research. Although overall recruitment remained low, predictions for future enrollment can be made from this study.
