Costs of managing severe hypoglycaemia in three European countries

Abstract

Objectives: To assess the costs of severe hypoglycaemic events (SHEs) in diabetes patients in Germany, Spain and the UK.

Methods: Healthcare resource use was measured by surveying 639 patients aged ≥16 years, receiving insulin for type 1 (n=319) or type 2 diabetes (n=320), who experienced ≥1 SHE in the preceding year. Patients were grouped by location of SHE treatment: group 1, community (family/domestic); group 2, community (healthcare professional); group 3, hospital. Costs were calculated from published unit costs applied to estimated resource use. Costs per SHE were derived from patient numbers per subgroup. Weighted average costs were derived using a prevalence database.

Results: Hospital treatment was a major cost in all countries. In Germany and Spain, costs per SHE for type 1 patients differed from those for type 2 patients in each group. Average SHE treatment costs were higher for patients with type 2 diabetes (Germany, €533; Spain, €691; UK, €537) than type 1 diabetes patients (€441, €577 and €236, respectively). Telephone calls, visits to doctors, blood glucose monitoring and patient education contributed substantially to costs for non-hospitalised patients.

Conclusions: Treatment of SHEs adds significantly to healthcare costs. Average costs were lower for type 1 than for insulin-treated type 2 diabetes, in all three countries.     

Retrospective database study to assess the economic impact of hip fracture in the United Kingdom

Objective:

Publications containing recent, real-world data on the economic impact of hip fractures in the UK are lacking. This retrospective electronic medical records database analysis assessed medication and healthcare resource use, direct healthcare costs, and factors predicting increased resource use and costs in adult UK hip fracture patients.

Methods:

Data were obtained from the Clinical Practice Research Datalink linked to the Hospital Episode Statistics for adult patients hospitalized for their first hip fracture between January 1, 2006 and March 31, 2011 (index event); healthcare costs were calculated from the National Health Service perspective using 2011–2012 cost data.

Results:

Data from 8028 patients were analyzed. Resource use and costs were statistically significantly higher in the year following fracture (mean total [standard deviation (SD)] cost £7359 [£14,937]) compared with the year before fracture (mean total [SD] cost £3122 [£9435]; p?Conclusions:

Although we did not capture all pre- and post-index costs and healthcare utilization, this study provides important insights regarding the characteristics of patients with hip fracture, and information that will be useful in burden-of-illness and economic analyses.     

Cost of illness associated with Niemann-Pick disease type C in the UK

Abstract

Objective: Niemann-Pick disease type C (NP-C) is a rare and devastating genetic disorder characterised by a range of progressive neurological symptoms, which imposes a burden on patients, family members, the healthcare system and society overall. The objective of this study was to assess direct and indirect costs associated with NP-C in the UK.

Methods: This was a non-interventional, retrospective, cross-sectional cohort study based on responses from patients and/or their carers/guardians recruited from a UK NP-C database. Resource use and direct medical, direct non-medical and indirect costs were evaluated using data collected via postal survey in October 2007, which included a Medical Resource Use questionnaire. Total annual costs per patient were estimated.

Results: In total, 18 Medical Resource Use questionnaires (29% response rate) were received and analysed. The mean total annual cost (SD) of NP-C per patient was £39,168 (£50,315); 46% were direct medical costs, to which home visits and residential care contributed 68% and 15%, respectively. Direct non-medical costs accounted for 24% of the average annual cost per patient, mainly due to specialist education, and indirect costs 30%. If only direct medical costs were considered, the mean annual cost (SD) per patient was reduced to £18,012 (£46,536).

Conclusions: The direct annual per-patient cost of NP-C illness in 2007 appears moderate when compared with other rare and severely disabling diseases. However, cost estimates may be conservative, since findings are limited by a small sample size, low survey response rate and potential recall bias. As demonstrated by this study, a substantial proportion of the cost is shifted from the healthcare system to the patient, family and non-medical providers. These findings highlight the need for treatments that can slow or stop disease progression in NP-C.     

Budget impact analysis of niraparib and olaparib for maintenance treatment of platinum-sensitive,recurrent ovarian cancer in the US

Aims: This study aimed to evaluate the budget impact of niraparib and olaparib in patients with platinum-sensitive, recurrent ovarian cancer from a US third party payer perspective.

Materials and methods: A budget impact model was constructed to assess the additional per member per month (PMPM) costs associated with the introduction of niraparib and olaparib, two poly ADP-ribose polymerase ribose polymerase (PARP) inhibitors recently approved to be used in platinum-sensitive, recurrent ovarian cancer patients with and without a gBRCA mutation. The model assessed both pharmacy costs and medical costs. Pharmacy costs included adjusted drug costs, coinsurance, and dispensing fees. Medical costs included costs associated with disease monitoring and management of adverse events from the treatment. Epidemiological data from the literature were used to estimate the target population size. The analysis used 1-year time frame, and patients were assumed on treatment until disease progression or death. All costs were computed in 2017 USD. One-way sensitivity analyses were conducted to evaluate the model robustness.

Results: In a hypothetical plan of 1,000,000 members, 206 patients were estimated to be potential candidates for niraparib or olaparib maintenance treatment after applying all epidemiological parameters. At listed 30-day supply WAC prices of $14,750 for niraparib and $13,482 for olaparib, budget impacts of these two drugs were $0.169 PMPM and $0.156 PMPM, respectively, most of which were contributed by pharmacy costs. Sensitivity analyses suggested that assumptions around market share, platinum-sensitive rate after first treatment, and WAC prices affected results the most.

Limitations: In this model, it was assumed that adopting niraparib and olaparib would not affect utilization of existing medications. Also, the estimated clinical parameters from clinical trials could differ from real-world data.

Abstract

Aims

Healthcare resource utilization (HRU) and costs in post-transplant lymphoproliferative disease (PTLD) patients following allogeneic hematopoietic stem cell transplant (HCT) were evaluated in the USA.     

Budget impact analysis of demineralized bone matrix in combination with autograft in lumbar spinal fusion procedures for the treatment of lumbar degenerative disc disease in Spain

Objective: To estimate the budget impact (BI) of introducing local autograft (LA) combined with demineralized bone matrix (LA?+?DBM) in lumbar spinal fusion (LSF) procedures to treat lumbar degenerative disc disease (LDDD) in Spain.

Methods: A decision tree model was developed to evaluate the 4-year BI associated with introducing LA?+?DBM putty to replace currently available grafting methods, including iliac crest bone graft (ICBG), LA alone, and LA combined with beta-tricalcium phosphate (LA?+?ceramics), with 30%, 40%, and 30% market shares, respectively. The analysis was conducted for a hypothetical cohort of 100 patients with LDDD receiving LSF, assuming LA?+?DBM would replace 100% of the standard of care mix. The fusion rates extracted from the literature were validated by an expert panel. Costs (€2017) were obtained from different Spanish sources. Budget impact and incremental cost per successful fusion were calculated from the perspective of the Spanish National Health System (NHS).

Results: Over 4 years, replacing currently available options with LA?+?DBM for 100 patients resulted in an additional cost of €12,330 (€123/patient), and an additional 14 successful fusions, implying a cost of €881 per additional successful fusion. When costs of productivity loss were included, the introduction of LA?+?DBM resulted in cost savings of €70,294 (€703/patient).

Limitations: The lack of high-quality, homogeneous, head-to-head research studying the efficacy of grafting procedures available to patients undergoing LSF, in addition to a lack of long-term follow-up in existing studies. Therefore, the number of fusions occurring within the model’s time horizon may be underestimated.

Conclusions: Acquisition costs of DBM were partially offset by costs of failed fusions, adverse events and reoperation when switching 100 hypothetical LDDD patients undergoing LSF procedures from standard of care grafting methods to LA?+?DBM from the perspective of the Spanish NHS. DBM cost was entirely offset when costs of lost productivity were considered.
