Shake No Bake: A Homemade Ultrasound Gel Recipe for Low-Resource Settings

Commercially produced ultrasound coupling gel is often a scarce resource in rural regions of low-income countries that use sonography as their main imaging modality and, when available, may be cost prohibitive. Various homemade gels were created and tested to assure image quality was not compromised. Glucomannan-based gel and guar gum-based gel had superior physical properties in initial testing and showed no substantial difference compared with commercially available ultrasound gel on subject and phantom imaging and analysis (P > .05 using a 1-tailed sign test). Neither gel required heating, attracted insects, damaged ultrasound transducers, stained samples of clothing, or had harmful effects to subjects.

Intermittent self catheterisation with hydrophilic, gel reservoir, and non-coated catheters: a systematic review and cost effectiveness analysis

OBJECTIVE

To determine the most effective and cost effective type of catheter for patients performing intermittent self catheterisation in the community.

DESIGN

Systematic review and meta-analysis. Results were incorporated into a probabilistic Markov model to compare lifetime costs and quality adjusted life years (QALYs).

DATA SOURCES

We searched Medline, Embase, and Cochrane and Cinahl databases from 2002 to 18 April 2011 to identify studies comparing hydrophilic, gel reservoir, and non-coated intermittent catheters. Earlier guidelines were used to identify papers published before 2002. To capture studies comparing clean and sterile non-coated intermittent self catheterisation, each database was searched from its date of inception to 18 April 2011.

MAIN OUTCOME MEASURES

Clinical outcomes included symptomatic urinary tract infection (UTI), bacteraemia, mortality, patient preference or comfort, and number of catheters used. The economic model included downstream complications of UTI and cost effectiveness was calculated as incremental cost per QALY gained.

RESULTS

Eight studies were included in the systematic review. Most were conducted in patients with spinal cord injuries, and most of the included patients were men. People using gel reservoir and hydrophilic catheters were significantly less likely to report one or more UTIs compared with sterile non-coated catheters (absolute effect for gel reservoir = 149 fewer per 1000 (95% confidence interval -7 to 198), P=0.04; absolute effect for hydrophilic = 153 fewer per 1000 (-8 to 268), P=0.04). However, there was no difference between hydrophilic and sterile non-coated catheters when outcomes were measured as mean monthly UTIs (mean difference = 0.01 (-0.11 to 0.09), P=0.84) or total UTIs at 1 year (mean difference = 0.18 (-0.50 to 0.86), P=0.60). There was little difference in the incidence of one or more UTIs for people using clean versus sterile non-coated catheters (absolute effect = 12 fewer per 1000 (-134 to 146), P=0.86). Although the most effective, gel reservoir catheters cost >£54,350 per QALY gained and are therefore not cost effective compared with clean non-coated self catheterisation.

CONCLUSION

The type of catheter used for intermittent self catheterisation seems to make little difference to the risk of symptomatic UTI. Given large differences in resource use, clean non-coated catheters are most cost effective. However, because of limitations and gaps in the evidence base and the designation of non-coated catheters as single use devices, we recommend a precautionary principle should be adopted and that patients should be offered a choice between hydrophilic and gel reservoir catheters.

[Impact of topical application of autologous platelet-rich gel on medical expenditure and length of stay in hospitals in diabetic patients with refractory cutaneous ulcers]

OBJECTIVE

To evaluate the potential financial benefit of topical application of autologous platelet-rich gel (APG) in treating diabetic refractory cutaneous ulcers.

METHODS

A single-center prospective randomized controlled trial was undertaken, with 117 patients with proven diabetic refractory cutaneous ulcers participating in the study. The patients who gave informed consents were randomly assigned into standard care group (n = 58) or standard care plus topical application of APG treatment group (n = 59). The outcome of healing and the medical expenditur and length of stay in the patients were compared between the two groups.

RESULTS

The APG-treated group had better healing outcomes than the standard-treated group. The APG-treated group had 84.750 (50/59) complete healing and 98.31% improvement, higher than the 68.97% (40/58) and 75.86%, respectively, in the standard-treated group (P = 0.026). The median length for healing in the APG-treated patients was 36 days, shorter than the 45 days in the standard-treated patients (P = 0.012). The total medical expenditure and length of stay in hospitals were not significantly different between APG-treated patients [yen 38223 (23070-57398); 57 (41-94) days] and standard-treated patients [yen 35070 (24436-53649); 58 (31.75-58.50) days) (P = 0.455 and 0.301 respectively). Spendings on items such as medicine, artificial treatment, materials, interventional operation, surgical procedures, laboratory tests and other auxiliary examination, accommodations, meals, nursing care and debridement and dressing change were similar between the two groups (P > 0.05).

CONCLUSION

There is an advantage for the topical application of APG on diabetic refractory cutaneous ulcers in terms of the healing outcomes. APG is a cost-effective choice for patients with diabetic refractory cutaneous ulcers.

A cost-effectiveness analysis of levodopa/carbidopa intestinal gel compared to standard care in late stage Parkinson's disease in the UK

OBJECTIVE

Evaluation of cost-effectiveness of levodopa/carbidopa intestinal gel (LCIG), compared to standard care (SC) in patients with advanced Parkinson's disease (aPD) in the UK.

DESIGN

Markov model to quantify costs and outcomes associated with LCIG versus SC in aPD patients at Hoehn and Yahr (H&Y) stages 3, 4 or 5 experiencing >50% OFF time per day. Time horizon was lifetime, LCIG treatment was assumed to last maximal 5 years after which patients revert to SC. Model comprised 12 aPD health states according to H&Y status and daily time spent in OFF state. Cost analyses are reported from a UK NHS and Personal Social Services perspective. Uncertainties were assessed through one-way sensitivity analyses.

COMPARATORS

LCIG, providing patients with continuous dopaminergic stimulation to maximise functional ON time during the day and SC, defined as medically determined best available oral medication.

MAIN OUTCOME MEASURES

Cost-effectiveness, based on quality adjusted life years gained, presented as an incremental cost-effectiveness ratio.

RESULTS

Lifetime analysis yields an incremental cost per QALY of £36,024 for LCIG compared to SC (incremental cost £39,644, QALY gain 1.1). Results were sensitive to time on treatment, health state on treatment initiation, and estimates of long term benefit (OWSA results from £32,127 to £66,421 per QALY). Findings must be considered in the context of the study limitations which were mainly due to data availability constraints.

CONCLUSIONS

LCIG is an effective treatment, reducing OFF time and improving quality of life in advanced PD. It provides value for money in levodopa-responsive aPD patients with severe motor fluctuations when no other treatment options are effective or suitable. Given LCIG is an orphan drug, it is reasonable to suggest that it may be considered cost-effective in the UK setting. However, further research is needed to complete current data gaps and increase robustness of the model.

Effect of guideline implementation on costs of hand hygiene

Hands of health care personnel frequently serve as vectors for the transmission of organisms between patients and are also a major reservoir for pathogens with antimicrobial resistance. Hand hygiene is one effective strategy to reduce health care associated infections. The purposes of this study were to (a) compare the costs of hand hygiene in hospitals with high and low hand hygiene compliance as well as high and low frequency of alcohol hand rub use; and (b) examine associations between hospital characteristics and hand hygiene compliance as well as frequency of alcohol hand rub use. Nursing and health care policy leaders should look for ways to promote sustained adherence to hand hygiene recommendations.

A comparison of sonographic image quality between the examinations using gel and olive oil, as sound media

OBJECTIVE

To compare the quality of real-time sonographic images obtained from the examinations using two different sound media, ultrasound gel and olive oil.

MATERIAL AND METHOD

A randomized controlled trial was conducted on the study population recruited from the routine ultrasound service with written informed consent. Each patient underwent scan using both ultrasound gel and olive oil as sound media, but only one media at a time. During each patient examination, the first type of sound media was randomly used and then followed by the other media. The sonographic images of the same plane were recorded as video clips for each type of sound media. The quality of images were blindly evaluated by one experienced sonographer and the quality of ultrasound images was rated as 0 (very poor), 1 (poor), 2 (fair), and 3 (good), respectively.

RESULTS

Of 346 cases (692 video clips), the image quality scores in ultrasound gel group and olive oil group were poor, fair, and good quality in 7, 182, and 157 and 9, 190, and 147 cases, respectively. The difference of quality scores between both groups was not statistically significant. (Chi square test; p = 0.687).

CONCLUSION

The quality of images obtained from the scan using olive oil is similar to that using ultrasound gel. Therefore, the olive oil may be used as alternative sound media for ultrasound examination. Furthermore, it could possibly be a preferred media because of its lower cost, pleasant smell, and it facility of cleaning.

Effectiveness and microbial contamination of an in-house alcohol-based hand rub

OBJECTIVES

To evaluate the effectiveness and contamination of an in-house alcohol-based hand rub in a real clinical setting and to compare its effectiveness in bacterial reduction with that of a commercial product.

MATERIAL AND METHOD

Effectiveness of the hand rub in bacterial reduction was compared to a commercial product using the modified antiseptic/disinfectant testing method of European Standard (EN 1500) in 12 volunteers. In-house alcohol-based hand rub in 50 clinical wards were serially collected and cultured to determine contamination.

RESULTS

The bacterial reduction factor of the hand rub was comparable to that of the commercial product. There was no organisms grown from serial cultures of the in-house alcohol-based hand rub in use for 28 days.

CONCLUSION

The in-house alcohol-based hand rub was effective and there was no contamination up to 28 days in use.

Lidocaine suppositories for prostate biopsy

OBJECTIVES

To evaluate, in a randomized prospective study, the efficiency of transrectal lidocaine suppositories to reduce pain during transrectal prostate biopsy, as suppositories allow longer for the agent to be effective.

PATIENTS AND METHODS

In all, 100 patients were randomized to receive either a placebo suppository or 10 mL of 2% (200 mg) lidocaine gel rectally 10 min before biopsy, or a suppository containing 60 mg lidocaine 1 or 2 h before biopsy. Costs (in euros) per application were 0.82 for gel and 0.63 for suppositories. In all patients the same 10-core biopsy technique was used. Pain was evaluated using a visual linear pain scale ranging from 0 to 100 points; the patient's side of the scale did not show the number of points.

RESULTS

The mean pain scores in the placebo, lidocaine gel, and lidocaine suppositories applied 1 h and 2 h before biopsy were 36.2, 40.9, 29.2 and 21.2, respectively. Thus patients with no anaesthesia reported 25% more pain than those receiving lidocaine suppositories 1 h before and 71% more pain than those receiving lidocaine suppositories 2 h before biopsy (P = 0.002).

CONCLUSIONS

Lidocaine suppositories at a lower dose and with longer to take effect can be used to reduce pain significantly more effectively than the commonly used gel. As suppositories are easy to use and cheap, they are recommended in daily routine prostate biopsy.

Cost effectiveness evaluation of ADCON-L adhesion control gel in lumbar surgery

Patients, physicians and third-party payers are becoming increasingly concerned with the economic burden resulting from advances in health care. Many economic health studies have focused on patients with sciatica and low back pain. An Economic Survey was conducted on lumbar discectomy patients who had been enrolled at least 12 months prior in a prospective randomized controlled clinical study of the adhesion control device ADCON-L. The survey measured patient satisfaction, return to work, additional medical treatment and medications after surgery. In addition, the duration of any re-operations from patients in the clinical study was analyzed. The results of the Economic Survey and re-operation time analysis show significant advantages for lumbar discectomy patients who received ADCON-L compared to control patients who did not. Patients who received ADCON-L not only had less scarring and less back pain than control patients but also were more satisfied with their surgeries and were able to return to work more often, as originally planned (p = 0.02). In addition, ADCON-L patients returned to their original jobs an average of 3.6 days sooner, changed jobs 50% less often, did not seek additional medical treatment as often, and took 20% less pain medication than did control patients (p = 0.01). In addition, patients receiving ADCON-L who required subsequent re-operation at the same lumbar space (e.g., reherniation) had a significantly shorter duration of secondary surgery (56.6 min vs. 130 min, p = 0.001) compared to patients who did not receive ADCON-L at the first surgery. Overall, ADCON-L patients demonstrated significant clinical and economic advantages over control patients. If all lumbar surgical patients in the US were to receive ADCON-L, annual savings to the health care system would exceed one half billion dollars.
