Background
In a developing country with limited resources, it is important to utilize the total cost visibility approach over the entire life-cycle of the technology and then analyse alternative options for acquiring technology.Methods
The present study analysed cost-effectiveness of an “In-house” magnetic resonance imaging (MRI) scan facility of a large service hospital against outsourcing possibilities. Cost per unit scan was calculated by operating costing method and break-even volume was calculated. Then life-cycle cost analysis was performed to enable total cost visibility of the MRI scan in both “In-house” and “outsourcing of facility” configuration. Finally, cost-effectiveness analysis was performed to identify the more acceptable decision option.Result
Total cost for performing unit MRI scan was found to be Rs 3,875 for scans without contrast and Rs 4,129 with contrast. On life-cycle cost analysis, net present value (NPV) of the “In-house” configuration was found to be Rs-(4,09,06,265) while that of “outsourcing of facility” configuration was Rs-(5,70,23,315). Subsequently, cost-effectiveness analysis across eight Figures of Merit showed the “In-house” facility to be the more acceptable option for the system.Conclusion
Every decision for acquiring high-end technology must be subjected to life-cycle cost analysis.Key Words: Technology assessment, Cost benefit analysis, Cost-effectiveness analysis 相似文献24.

Objectives
To evaluate the effect of obstructive sleep apnea (OSA) surgery on long-term (5-year) subjective outcomes, including sleep disordered breathing (SDB) symptoms and other complications, in patients with OSA.Methods
We enrolled patients who underwent diagnostic polysomnography for OSA between January 2006 and December 2006 in ten hospitals. Patients either were treated for OSA or were not treated for OSA. All patients completed a brief telephone survey regarding their SDB signs and symptoms (e.g., snoring, apnea, nocturnal arousals, and daytime sleepiness), positive airway pressure (PAP) compliance, and any adverse effects of either the surgery or PAP. A positive subjective outcome for either surgery or no treatment was taken to be the alleviation of apnea, defined as a ≥50% increase in score. A positive subjective outcome (compliance) for PAP was defined as a PAP usage of ≥4 hours per night and ≥5 days per week.Results
A total of 229 patients were included in this study. Patients were divided into three groups: a surgery group (n=87), a PAP group (n=68), and a control (untreated) group (n=74). The surgery group exhibited significant improvement in all SDB symptoms compared with the control group. The long-term subjective outcomes of the surgery (52.9%) and PAP (54.4%) groups were significantly better than those of the control group (25.0%). The subjective outcome of the surgery group was not significantly different from that of the PAP group. The overall surgical complication rate was 23.0% (20 of 87) in the surgery group, and 55.0% (22 of 40) of all patients with PAP experienced adverse effects.Conclusion
The extent of SDB symptoms was consistently improved in patients with OSA at 5 years postsurgery. Information about the potential long-term subjective outcomes should be provided to patients when considering surgery. 相似文献26.

Purpose
To compare preoperative and postoperative ocular biometry in patients with iris-fixated phakic intraocular lens (pIOLs): Artisan and Artiflex.Materials and Methods
This study included 40 eyes with Artisan and 36 eyes with Artiflex pIOL implants. Anterior chamber depth (ACD) and axial length (AL) were measured by applanation ultrasonography (A-scan) and partial coherence interferometry (IOLMaster) preoperatively and 3 months after pIOL implantation.Results
ACD measurements after Artisan or Artiflex pIOL implantation were smaller than preoperative measurements. Specifically, the difference after Artisan pIOL implantation was -1.07±0.17 mm by A-scan and -0.08±0.08 mm by IOLMaster. The difference after Artiflex pIOL implantation was -1.31±0.15 mm by A-scan and -0.05±0.07 mm by IOLMaster. After Artisan pIOL implantation, differences in AL measurements by A-scan were insignificant (difference: -0.03±0.15 mm), whereas postoperative AL measurements by IOLMaster were significantly longer than preoperative measurements (difference: 0.12±0.07 mm). After Artiflex pIOL implantation, AL measurements by both A-scan and IOLMaster were significantly longer than preoperative measurements (difference: 0.09±0.16 mm by A-scan and 0.07±0.10 mm by IOLMaster). In the Artiflex group, differences in AL measurements by A-scan correlated with the central thickness of the Artiflex pIOL.Conclusion
ACD and AL measurements were influenced by iris-fixated phakic IOL implantation. 相似文献27.

[Purpose] The purposes of this study were to investigate the influences of position on
%MVIC of spinal stability muscles to establish for the most effective breathing pattern
for activation of spinal stability muscles in order to provide an additional treatment
method for use in spinal stability exercise programs. [Subjects and Methods] Thirty-three
healthy subjects performed quiet breathing and four different forced respiratory maneuvers
(FRM); [pursed lip breathing (PLB), diaphragmatic breathing (DB), combination breathing
(CB) and respiration muscle endurance training (RMET)] in both standing and sitting
positions. %MVIC of them (the multifidus (MF), erector spinae (ES), internal
oblique/transversus abdominis (IO/TrA), external oblique (EO), rectus abdominis (RA)
measured. [Results] IO/TrA, MF and EO showed greater activation in standing than in
sitting, while RA and ES showed greater activation in sitting than in standing. RMET
induced significantly greater activation of spinal stability muscles then other breathing
patterns. %MVIC changes of muscle activities induced by FRM were independent of position
with a few exceptions. [Conclusion] The increased respiratory demands of FRM induced
greater activation of spinal stability muscles than QB. RMET was found to be the most
effective breathing pattern for increasing the activation of the spinal stability
muscles.Key words: Spinal stability muscles, Position, Forced respiratory maneuvers 相似文献

The reference interval for plasma total homocysteine (tHcy) and serum folate concentrations were estimated. Total of 3,154 reference individuals (1,029 men and 2,125 women) were selected based on stringent exclusion criteria. For plasma tHcy concentration (µM/L), reference values (median [5-95 percentile]) were 7.72 (5.03 to 13.80) and 6.09 (3.95-10.19) in men and women, respectively. For serum folate concentration (nM/L), reference values were 23.71 (11.73-38.44) and 28.95 (15.23-40.44) in men and women, respectively. The tHcy levels of both genders in the present study were lower than those in previous reports from other countries and Korea.
