Economic evaluation of poison centers: a systematic review
Galvao T F, Silva E N, Silva M T, Bronstein A C, Pereira M G; International Journal of Technology Assessment in Health Care 2012; 28(2):86–92
Study Question: To undertake a systematic review of the literature on economic evaluations of poison
centers (PCs). Economic evaluation studies that compared PCs with an alternative intervention from the
perspectives of society, the payer and the healthcare system were eligible for inclusion. There were no
constraints on language or type of publication. The outcomes of interest were economic evaluations results
(cost–benefit ratios, incremental cost-effectiveness ratios, incremental cost–utility ratios, and incremental
costs). Literature was searched up to November 2011. Data extracted included the country and year in which
the cost data were col ected, type of economic evaluation, time horizon, perspective, population,
intervention, alternative intervention, discount rate, sensitivity analysis, scenarios adopted, costs measured,
effectiveness considered and economic results. For papers that any of these data were missing, attempt was
made to contact the corresponding author to obtain the needed information.
Patient Group: Poisoned individuals contacting the poison center for help and advice.
Key Results: Of th
e 422 non-duplicated studies retrieved, 9 met the eligibility criteria. In all studies, the
presence of PCs was compared with a scenario of their absence. Eight studies used cost–benefit analysis
(CBA) and one used a cost-effectiveness analysis (CEA). The cost–benefit ratios ranged from 0.76 to 7.67,
while the CEA showed that each successful outcome achieved by a PC avoids a minimum of US$12,000–
US$56,000 in other healthcare spending. The authors conclude that the results of their review show that PCs
are economically viable and go on to suggest that an investment in PCs is a rational public health policy
approach that contrasts the current trend of reducing spending on PCs.
HEED News & Reviews Incidence and cost of serious fall-related injuries in nursing homes
Quigley P A, Campbell R R, Bulat T, Olney R L, Buerhaus P, Needleman J; Clinical Nursing Research 2012;
21(1):10–23 Study Question: To estimate the cost of fal -related injuries (FRIs), with a nursing home as the source of
admission, in Veterans Administration (VA) and non-VA facilities. The study involved a retrospective analysis
Patient Group: Nursing home patients admitted to VA and non-VA facilities with fall-related injuries.
Key Results: Over a 3-year period, there were 2400 admissions to VHA hospitals for FRI, with 55.4% hip
fractures and10.1% intracranial injuries, with an average cost of US$23,723 per admission. Over a 9-year
period, there were 141,308 admissions from nursing homes to non-VA hospitals for FRIs, with 38.8% hip
fractures, 35.7% other fractures and 11.1% intracranial injuries, with an average cost of US$31,507 per
admission. Prevention program emphasis should shift away from a focus on preventing falls as a measure of
quality care to decreasing FRIs. These findings support implementation of injury prevention programs for the
elderly that reduces risk for injury as the primary outcome.
Estimating the lifelong health impact and financial burdens of different types of lung
Yang S C, Lai W W, Su W C, Wu S Y, Chen H H, Wu Y L, Hung M C, Wang J D; BMC Cancer 2013; 13:579
Study Question: To estimate the lifelong health impacts and financial burdens of different types of lung
cancer in Taiwan. The study uses a combination of primary data collection and analysing data from pre-
existing databases to estimate financial burden and quality-adjusted life expectancy (QALE). Specifically, the
study abstracted data from the National Cancer Registry for survival analysis, combined this with the
national life tables to extrapolate the survival function to lifetime, collected quality-of-life (QoL) and costs
data from lung cancer patients in the study hospital, and integrated the survival function with the QoL and
costs to estimate the life expectancy, QALE, loss-of-QALE, and lifetime health care expenditures per case of
Patient Group: Patients with lung cancer in Taiwan. The EQ-5D-5L was administered to 1314 patients to
Key Results: The losses of QALE for patients with small cell lung cancer, squamous cell carcinoma and
adenocarcinoma were 13.69, 12.22 and 15.03 QALYs, respectively. The corresponding lifetime healthcare
expenditures were US$18,455 ± 1,137, 20,599 ± 1,787, and 36,771 ± 1,998, respectively. In conclusion,
the authors point out that the lifelong health impact and financial burdens in Taiwan are heavier for
adenocarcinoma than for squamous cell carcinoma and suggest that the cost-effectiveness of prevention
programmes could be directly compared with that of treatment strategies to improve patient value.
HEED News & Reviews Are educational interventions to prevent catheter-related bloodstream infections in intensive care unit cost-effective?
Cooper K, Frampton G, Harris P, Jones J, Cooper T, Graves N, Cleland J, Shepherd J, Clegg A, Cuthbertson B H;
Journal of Hospital Infection 2014; 86(1):47–52
Study Question: There is increasing interest in evidence-based educational interventions in central venous
catheter care. It is unclear how effective these are at reducing the risk of bloodstream infections from the
use of intravascular catheters (catheter-BSIs) and the associated costs and health benefits. Therefore, the
aim of this study was to estimate the additional costs and health benefits from introducing such
interventions and the costs associated with catheter-BSIs. In order to do this, a comprehensive
epidemiological and economic review was performed to develop the parameters for a decision analytic
model to assess the cost-effectiveness of introducing an educational intervention compared with clinical
practice without the intervention. The model follows the clinical pathway of cohorts of patients from their
admission to an intensive care unit (ICU), where some may acquire catheter-BSI. The analysis was conducted
from the perspective of the UK National Health Service (NHS).
Patient Group: Hypothetical cohorts of 100 adult patients treated with an educational intervention, such as
intravascular catheters, or clinical practice without the intervention. Data for the model were taken from
adult patients in ICUs in England and Wales. Data were also taken from a systematic review of the clinical
effectiveness of the educational intervention, literature searches, and through discussion with clinical
Key Results: The base-case results show that for every 100 patients admitted to intensive care, the CVC care
bundle cohort has 0.8 fewer catheter-BSIs than the current clinical practice cohort, and 0.3 fewer deaths
during intensive care, which leads to an increased survival of 3.6 years and 2.7 QALYs. The additional cost for
each catheter-BSI was £3940. The CVC care bundle is more effective and less costly (£1557) than current
practice, with an additional cost per life-year saved of £439 and a cost per QALY gained of £573. The cost
savings are largely as a result of the savings from reduced length of stay in the ICU. The additional cost per
catheter-BSI averted was £1976. With the exception of the catheter-BSI incidence rate and the additional
ICU length of stay for patients with catheter-BSI, the CVC care bundle is cheaper for all parameter values,
and the model results are most sensitive to changes in these two parameters. Changes to these two
parameters produced cost-effectiveness estimates that remained within acceptable limits. Based on these
findings, the authors conclude that introducing an additional educational intervention improved patient life
expectancy and reduced overal costs. The model results suggest that the cost of introducing the
interventions wil be outweighed by savings related to reduced ICU bed occupancy costs.
