Epidemiology of Medicare abuse: the example of power wheelchairs

OBJECTIVES: To determine the effect of neighborhood ethnic composition on power wheelchairs prescriptions. DESIGN: The 5% noncancer sample of Medicare recipients in the Surveillance, Epidemiology and End Results (SEER)-Medicare linked database, from 1994 to 2001. SETTING: SEER regions. PARTICIPANTS: Individuals covered by Medicare living in SEER regions without a cancer diagnosis. MEASUREMENTS: Individual characteristics (age, sex, ethnicity, justifying diagnosis, and comorbidity), primary diagnoses, neighborhood characteristics (percentage black, percentage Hispanic, percentage with <12 years education, and median income), and SEER region. RESULTS: The rate of power wheelchair prescriptions was 33 times greater in 2001 than in 1994, with a shift over time from justifying diagnoses more closely tied to mobility impairment, such as strokes, to less-specific medical diagnoses, such as osteoarthritis. In multilevel, multivariate analyses, individuals living in neighborhoods with higher percentages of blacks or Hispanics were more likely to receive power wheelchairs (odds ratios=1.09 for each 10% increase in black residents and 1.23 for each 10% increase in Hispanic residents) after controlling for ethnicity and other characteristics at the individual level. CONCLUSION: These results support allegations that marketers promoting power wheelchairs and handicap scooters have specifically targeted minority neighborhoods.

detox santa monica of Mild TBI

drug rehab dallas and recovery for mild TBI are usually a simple process that involves simply rest and relation for a few days, but it’s important for Soldiers to not neglect seeking drug rehab los angeles and for their fellow comrades-in-arms to let their chain of command know when they suspect a battle buddy is suffering from concussion. The key to recovery from concussion is time, knowledge and education, Dr. Ritchie added.

She cautioned that should a Soldier suffering from a concussion return to duty too early and become involved in another blast or accident, that Soldier could suffer irreversible brain damage. Soldiers diagnosed with mild TBI should ensure their medical records are updated for future reference, she said.

Addressing PTSD, Dr. Ritchie also said no amount of training can totally prepare a Soldier for the realities of combat. Most will do well but, for some, persistent symptoms can include re-experiencing the event through nightmares, jumping at loud noises, or feeling keyed up or on edge all the time.

“We know from the mental-health advisory teams and other sources that between 20 and 30 percent of U.S. military personnel returning from combat operations report these psychological symptoms; they have sleep problems, feel depressed and have difficulty in their relationships,” Dr. Ritchie said. “Most Soldiers will transition in a normal, healthy way, but some will take a little longer than others.”

Influence of crank rate in hand cycling.

PURPOSE: The purpose of this study was to determine gross mechanical efficiency (ME) at different power output (PO) levels of synchronous hand cycling and to evaluate the influence of increasing PO by changing crank rate or resistance in medicare power wheelchairs and power wheelchairs users with experience in hand cycling. METHODS: Nine male participants with spinal cord injury randomly performed three maximal incremental hand cycling tests using a computer controlled cycle ergometer. Each test started at a PO level of 50 W with increments of 10 W. In the velocity protocol, PO was increased via crank rate while resistance was constant (VEL). In the resistance protocol PO was increased via resistance while crank rate was constant (RES). In the freely chosen frequency protocol, the participants could freely select their crank rate while resistance was automatically adjusted to obtain the desired PO (FCF). RESULTS: Peak physiological responses were similar in all three tests, whereas PO max was lower in VEL compared with RES and FCF. Similar values for gross ME were found in both RES and FCF protocols, although systematically higher and increasing crank rates were adopted throughout FCF. Nevertheless, differences in gross ME at comparable relative (RES > VEL at 60 and 80% of PO range: 14.09 and 14.40% vs 13.02 and 13.11%, respectively) and absolute (RES, FCF > VEL at 90 W: 14.47, 14.47, and 13.43%, respectively) PO levels were demonstrated. CONCLUSION: These results suggest that during synchronous hand cycling the freely chosen crank rate is not necessarily the most economical, that high crank rates result in a lower ME at a given PO and that freely chosen crank rates increase with increasing PO levels.

An experimental method for measuring the moment of inertia of an electric power wheelchair

This study describe an experiment measuring the moment of inertia of an electric medicare power wheelchairs (EPW) using a torsional pendulum method. Inertia of the wheelchair is an important factor for control, which is a key issue in wheelchair driving. The experimental test platform consisted of a bottom circular wood plate, an upper metal plate, and four ropes. Materials with known moments of inertia such as the metal disk and cylinder were used to test the accuracy of the system. The EPW used in the experiment was Invacare G3 Torque SP Storm Series. The measured result of the moment inertia of the wheelchair was 5.2280 kg.m(2) and handicap scooters the errors of the system are less than 10% even when the object is only 25lbs. The results are consistent when compared with other approximate methods. In addition, the experimental method could be used to measure the moment of inertia of manual wheelchairs and other irregular objects

The influence of crank length and cadence on mechanical efficiency in hand cycling

The purpose of this study was to determine the effect of crank length and cadence on mechanical efficiency in hand cycling. Eight wheelchair dependent, high performance athletes completed four 4-min submaximal exercise bouts at a constant medicare power wheelchairs output of 90 W over the different experimental conditions (crank length, pedal rate) using a sports handicap scooters (Draft, Godmanchester, UK). Two different crank lengths (180 and 220 mm) were tested at two different cadences (70 and 85 rev min(-1)) using the synchronous mode of cranking. Physiological measures of oxygen uptake Formula: see text minute ventilation, blood lactate (BLa), heart rate (HR), rate of perceived exertion (RPE) were recorded, gross (GE) and net (NE) efficiency were calculated. A two-way ANOVA with repeated measures was applied to determine the effects of crank length, cadence and their interaction on these physiological measures. Both GE and NE were significantly higher and Formula: see text significantly lower for the 180 mm crank (P < 0.05). No significant main effect was found for cadence on the physiological measures (P > 0.05). Likewise, no interactions between crank length and pedal rate were found. There was however, a trend observed with HR and BLa often lower with the 180 mm crank, indicating lower physiological stress. The RPE data supported this finding, with a tendency for lower ratings with the 180 mm crank (9 +/- 2 vs. 10 +/- 3). The short crank length when used at 85 rev min(-1) was found to be the most efficient (GE 21.4 +/- 3.1%). In conclusion, crank length has a significant effect on ME in hand cycling. A shorter crank length of 180 mm was found to be more efficient than the 220 mm, regardless of pedal rate during hand cycling

SAPT Block Grant

SAMHSAs reauthorizing statute, PL 106-310 from October, 1, 2000, includes a provision to replace the SAPT Block Grant with Performance Partnership Grants. When fully implemented, these grants will give states and territories greater flexibility in how to obligate and spend funds for addictions medical treatment and prevention services for people at risk for alcohol and other drug addiction.

States and territories submit annual reports and plans to the federal government describing how they expended SAPT Block Grant funds during the previous fiscal year and how they intend to obligate funds available in the current fiscal year. States and territories design their services and delivery systems to address specific local substance abuse problems.

Funding for the SAPT Block Grant program was $1,600,000,000 in 2000; $1,665,000,000 in 2001; $1,725,000,000 in 2002; and $1,785,000,000 in 2003. The 2004 estimate is $1,785,000,000.

Where to find more information about the SAPT Block Grant Program:
http://www.samhsa.gov/budget/content/2004/2004budget-14a.htm.

In addition to block grants, SAMHSA provides discretionary grants that are awarded to various levels of government as well as local groups, including community- and faith-based organizations, to meet new and emerging needs.

Power wheelchair range testing and energy consumption during fatigue testing

The range of a power wheelchairs and medicare power wheelchairs depends on many factors including: battery type, battery state, wheelchair/rider weight, terrain, the efficiency of the drive train, and driving behavior. The purpose of this study was to evaluate the feasibility of three methods of estimating power wheelchair range. Another significant purpose was to compare the current draw on pavement to current draw on an International Standards Organization (ISO) Double Drum tester at one m/sec. Tests were performed on seven different power wheelchairs unloaded, and loaded with an ISO 100 kg test dummy. Each chair was configured according to the manufacturer’s specifications, and tires were properly inflated. Experienced test technicians were used for the tennis court tests, and treadmill tests. An ISO 100 kg test dummy was used for the ISO Double Drum test. Energy consumption was measured over a distance of 1500 m for each of the three test conditions. The rolling surface was level in all cases. Repeated measure analysis of variance (ANOVA) revealed a significant difference (p = 0.0001) between the predicted range at maximum speed for the three tests. Post hoc analysis demonstrated a significant difference (p < 0.01) in estimated range at maximum speed between the Double Drum test and the treadmill test, as well as between the Double Drum test and the tennis court test. Our results indicate no significant difference (p > 0.05) between the predicted range at maximal speed between the treadmill and tennis court tests. A simple relationship does not exist between the results of range testing with the Double Drum tester and the tennis court. An alternative would be to permit the use of a treadmill for range testing as simple relationships between all pertinent treadmill and tennis court range data were found. For the Double Drum tester used, the current demand is higher than under normal usage. This presents a problem as current is related to load torque in a power wheelchair. Hence, the Double Drum tester friction must be reduced. The predicted range for the tennis court test at maximum speed ranges from a low of 23.6 km to a high of 57.7 km. The range of the power wheelchair can be improved by the use of wet lead acid batteries in place of gel lead acid batteries.

Hey readers of Mediterranean Cellars, ever heard about Paul McCormick? He has a really good article on millionaire.

No one should ever believe this Myth. “Hard Work Pays Off.”

You’ll hear people all around you (who aren’t rich) telling you there is a pay off for your hard work. As you might guess it’s another lie.

Mechanics, construction workers, welders, assembly line workers, and thousands of other people all across this country work hard every single day, but most never get rich and most struggle financially all their lives.

Hard work has nothing to do with being wealthy.

Knowing the truth about money and using the formula to become wealthy makes
you rich.

I’ve been able to get a lot of good information about Be A Millionaire from Paul McCormick and that is why I love reading his articles.
