The cost-effectiveness of unilateral cochlear implants in UK adults.

OBJECTIVE: The National Institute for Health and Care Excellence (NICE) updated its eligibility criteria for unilateral cochlear implants (UCIs) in 2019. NICE claimed this would not impact the cost-effectiveness results used within its 2009 technology appraisal guidance. This claim is uncertain given changed clinical practice and increased healthcare unit costs. Our objective was to estimate the cost-effectiveness estimates of UCIs in UK adults with severe to profound hearing loss within the contemporary NHS environment. METHODS: A cost-utility analysis employing a Markov model was undertaken to compare UCIs with hearing aids or no hearing aids for people with severe to profound hearing loss. A clinical pathway was developed to estimate resource use. Health-related quality of life, potential adverse events, device upgrades and device failure were captured. Unit costs were derived mostly from the NHS data. Probabilistic sensitivity analysis further assessed the effect of uncertain model inputs. RESULTS: A UCI is likely to be deemed cost-effective when compared to a hearing aid (£11,946/QALY) or no hearing aid (£10,499/QALY). A UCI has an 93.0% and 98.7% likelihood of being cost-effective within the UK adult population when compared to a hearing aid or no hearing aid, respectively. ICERs were mostly sensitive to the proportion of people eligible for cochlear implant, discount rate, surgery and device costs and processor upgrade cost. CONCLUSION: UCIs remain cost-effective despite changes to clinical practice and increased healthcare unit costs. Updating the NICE criteria to provide better access UCIs is projected to increase annual implants in adults and children by 70% and expenditure by £28.6 million within three years. This increased access to UCIs will further improve quality of life of recipients and overall social welfare.

Risk factors for Pseudomonas aeruginosa infections in Asia-Pacific and consequences of inappropriate initial antimicrobial therapy: A systematic literature review and meta-analysis.

OBJECTIVES: Treating infections of Gram-negative pathogens, in particular Pseudomonas aeruginosa, is a challenge for clinicians in the Asia-Pacific region owing to inherent and acquired antimicrobial resistance. This systematic review and meta-analysis provides updated information on risk factors for P. aeruginosa infection in Asia-Pacific as well as the consequences (e.g. mortality, costs) of initial inappropriate antimicrobial therapy (IIAT). METHODS: Embase and MEDLINE databases were searched for Asia-Pacific studies reporting the consequences of IIAT versus initial appropriate antimicrobial therapy (IAAT) in Gram-negative bacterial infections as well as risk factors for serious P. aeruginosa infection. A meta-analysis of unadjusted mortality was performed using a random-effects model. RESULTS: A total of 22 studies reporting mortality and 13 reporting risk factors were identified. The meta-analysis demonstrated that mortality was significantly lower in patients receiving IAAT versus IIAT, with a 67% reduction observed for 28- or 30-day all-cause mortality (odds ratio=0.33, 95% confidence interval 0.20-0.55; P<0.001). Risk factors for serious P. aeruginosa infection include previous exposure to antimicrobials, mechanical ventilation and previous hospitalisation. CONCLUSION: High rates of antimicrobial resistance in Asia-Pacific as well as the increased mortality associated with IIAT and the presence of risk factors for serious infection highlight the importance of access to newer and appropriate antimicrobials.

Counting the costs: case management implications of spinal cord stimulation treatment for failed back surgery syndrome.

PURPOSE/OBJECTIVES: The purpose of this article is to review clinical and health economic evidence supporting the use of spinal cord stimulation (SCS) for failed back surgery syndrome (FBSS) and to discuss implications for case managers' decision making. PRIMARY PRACTICE SETTINGS: Primary settings include hospital and home environments. FINDINGS/CONCLUSIONS: Patients with FBSS experience persistent or recurring pain in the lower back, legs, or both after one or more spinal surgeries. Surgical revision and nonsurgical FBSS therapies often result in minimal or no clinical improvement, and reoperations often result in more pain. The efficacy and safety of SCS have improved as a result of earlier intervention, technological advances, and increased awareness of SCS proper patient selection. A recent randomized controlled trial (RCT) demonstrated that at mean 3-year follow-up, SCS achieves significantly more pain relief and treatment satisfaction and lower opiate analgesic use than reoperation in patients with FBSS. Another RCT demonstrated that at 6-month follow-up, more patients with FBSS achieve pain relief, enhanced quality of life, improved functioning, and higher treatment satisfaction levels with SCS than with conventional medical management (CMM). Health-economic FBSS studies show that SCS is more cost-effective than CMM or reoperation. SCS is a well-established FBSS treatment option with demonstrated efficacy and cost-effectiveness in selected patients. IMPLICATIONS FOR CM PRACTICE: Case Managers should consider recommending SCS as one modality prior to reoperation in patients with FBSS who meet the clinical criteria for its appropriate use.
