After controlling for other variables, including criminal history, African Americans in Cook County, Illinois were approximately 1.

Young African-American men in Ohio had lower odds of pretrial release on their own recognizance, had higher bond amounts, and higher odds of incarceration relative to other demographic subgroups (Wooldredge 2012). The exercise of federal prosecutorial discretion with respect to charging decisions, motions for mitigated sentences based on substantial assistance by the defendant in the prosecution of others, and plea bargaining has led to racial disparities that affect sentences (Baron-Evans and Stith 2012, pp. Rehavi and Starr (2012) found that federal prosecutors were more likely to charge more serious offenses against black than white arrestees, including for offenses carrying mandatory minimum penalties. Ulmer and his colleagues found racial differences in downward departures under the federal guidelines, whether initiated by prosecutors or judges (Ulmer, Light, and Kramer 2011). Researchers concluded that the defendant’s race influenced the likelihood of incarceration in 15 studies of drug offender sentencing. All else considered, white felony drug offenders in North Carolina received less severe punishment than blacks or Hispanics (Brennan and Spohn 2011). The effects of race on sentencing decisions is particularly notable when the studies take account of age, gender, or socioeconomic status (Spohn and Hollerman 2000; Doerner and Demuth 2010; Spohn 2011). Doerner and Demuth’s study of sentencing decisions in federal courts found that young black and Hispanic males receive the harshest sentences of all racial/ethnic/gender-age subgroups and that the effects of race and ethnicity were larger in drug than in nondrug cases (Doerner and Demuth 2010, p. In 2003, the United States Sentencing Commission reported that black drug defendants were 20 percent more likely to be sentenced to prison than white drug defendants (U. In its annual report for 2010, the United States Sentencing Commission reported that black (30. Blacks had higher average sentences than whites or Hispanics for powder and crack offenses, regardless of whether they were sentenced under the mandatory minimum provisions (U. Much of the research on racial disparities in case outcomes has sought to tease out the extent to which racial differences reflect the influence of legally irrelevant factors such as race, gender, and age. Yet research also shows that ostensibly race-neutral, legally relevant factors such as prior criminal records yield racial disparities. Sentencing enhancements for repeat offenders are ubiquitous, both formally in sentencing laws and informally in sentencing practices. They may play a particularly significant role in drug cases because many drug defendants have significant histories of prior offending. According to the Bureau of Justice Statistics, for example, 66 percent of felony defendants arrested on drug offenses have prior convictions; 14 percent have 10 or more prior convictions (Cohen and Kyckelhahn 2010). Although there are no national data providing a breakdown of prior criminal records for drug offenders by race, the higher drug arrest rates for African Americans suggest they are more likely to have prior convictions. Frase (2009) found that criminal history was the single most important factor contributing to racial disparities in Minnesota—disparities that were substantially greater than at arrest and conviction. Black criminal history scores were higher than white within all major offense categories and were especially higher for drug offenders. Criminal history influences the exercise of prosecutorial and judicial discretion in ways that disproportionately burden blacks. Spohn and Spears (2001) found that black drug offenders with prior felony convictions in Miami had higher odds of incarceration than white drug offenders with the same criminal record. Crawford, Chirico, and Kleck (1998) found that “the combination of being Black and being charged with a drug offense substantially increases the odds of being sentenced as habitual” (p. Revisiting Crawford’s study a decade later, Crow and Johnson (2008) found that “race (and ethnicity) still matter for habitual-offender designations” (p. Black and Hispanic defendants are significantly more likely to be prosecuted as habitual offenders than white defendants, and the odds were greatest for black and Hispanic drug defendants (Crow and Johnson 2008, p. More research is needed to understand the effects of prior criminal records on drug offender sentencing. Black drug arrestees in New York are more likely than whites to have prior convictions, given that blacks are far more likely to be arrested on drug charges. Frase (2009) points out that the emphasis given to prior criminal records in sentencing is a policy choice and one that appears due for reconsideration. Although there is widespread support for imposing longer sentences on repeat offenders (Roberts 1997), there is scant evidence that habitual offender sentencing enhances public safety or reduces crime. Crow and Johnson (2008) conclude, “given the findings of over a decade of habitual-offender research that demonstrates racial and ethnic discrimination (unwarranted disparity), it may be time to reconsider the utility of habitual-offender statutes” (p. Rehavi and Starr (2012), make the same point, “the heavy weight placed on criminal history in [federal] sentencing law is also a subjective policy choice with racially disparate consequences. Legislators and the Sentencing Commission members who are concerned about incarceration rates among black men may wish to consider these distributional consequences when assessing the costs and benefits of these aspects of the sentencing scheme” (p. Drug laws typically prescribe higher sentences for sales and manufacturing than for possession. Defendants convicted of sale are more likely to go to prison than are those convicted of possession, and the sentences are typically longer (Cohen and Kyckelhahn 2010). Blacks are disproportionately likely to be arrested for sales offenses, so it is likely that harsher sentencing for sales contributes to the disparities in sentencing outcomes. Racial disparities in the incarceration of drug offenders also reflect legislative priorities. Because black Americans are more likely to be sentenced for federal crack offenses, they are disproportionately burdened by the higher crack sentences.

Race, Crime, and Punishment There are racial disparities at every stage of drug case processing in state and federal criminal justice systems. As the Seattle research illustrates, race influences perceptions of the danger posed by the different people who use and sell illicit drugs, the choice of drugs that warrant the most public concern, and the choice of neighborhoods in which to concentrate drug law enforcement resources. Yet race is a powerful lens that colors what we see and what we think about what we see. In the United States, images of crime, danger, drug offenders, and criminals are deeply racialized. Tonry (2011) and Provine (2007) summarize studies on the effects of racial attributions and stereotypes on people’s perceptions, attitudes, and beliefs and the ways race correlates with policy choices. Whites may no longer consciously believe in the inherent racial inferiority of blacks, but they nonetheless harbor unconscious racial biases (Rachlinski et al. In one typical study, police officers shown black and white photographs of male university students and employees thought more of the black than white faces looked criminal; the more stereotypically black the face was, the more likely the officers thought the person looked criminal (Eberhardt et al. Unconscious notions and attitudes are most likely to influence criminal justice decisions that have to be made in the face of uncertainty and inadequate information or in ambiguous or borderline cases. To recognize the influence of race on social psychology, unconscious cognitive habits, and “perceptual shorthand” (Hawkins 1981, p. Race helps explain the development and persistence of harsh drug laws and policies. White Americans tend to support harsher punishments more than do blacks, a predilection that has strong roots in racial hostilities, tensions, and resentments (Tonry 2011, p. Researchers have found that whites with racial resentments toward blacks are far more likely to support punitive anticrime policies and that whites are twice as likely as blacks to prefer punishment over social welfare programs to reduce crime (Unnever, Cullen, and Johnson 2008).

Guidelines for assessing an economic analysis of clinical care Was a broad enough viewpoint adopted? Is there a speciﬁed point of view cheap 160 mg malegra fxt plus amex impotence yoga pose, either a hospital generic malegra fxt plus 160 mg otc erectile dysfunction doctors in ny, health insurance entity buy malegra fxt plus paypal erectile dysfunction foods, min- istry of health, or preferably society as a whole, from which the costs and effects are being viewed? Often these studies compare usual fee for service or third- party insurance against managed-care costs. However, the comparison may sim- ply be for the costs of the treatments only without a speciﬁc viewpoint on who is paying for them or how much is being reimbursed. There is a disconnect between costs and charges in health-care ﬁnances because of the large amount of uncompensated and negotiated care that is deliv- ered. Costs are the amount of money that is required to initiate and run a particular intervention. However, when using simple costs only, the cost of treating non-insured patients must be fac- tored into the accounting. It should be possible from reading the article’s methods to set up the same pro- gram in any comparable setting. This requires a full description of the process of setting up the program, the costs and effects of the program, and how these were measured. Typically two treatment options or treatment as opposed to non-treatment are considered in a cost- effectiveness analysis. Using treatments that are no longer in common use will give a biased result to the analysis. There should be hard evidence from well-done randomized clinical trials to show that the interven- tion is effective, and this should be explicitly stated. Where not previously done, a systematic review or meta-analysis should be performed as part of the anal- ysis. A cost-effectiveness analysis should not be done based on the assump- tion that because we can do something it is good. Does the analysis identify all the important and relevant costs and effects that could be important? Were credible measures selected for the costs and effects that were incorporated into the analysis? On the cost side this includes the actual costs of organization and setting up a program and continuing operations, addi- tional costs to patient and family, costs outside the health-care system like time lost from work and decreased productivity, and intangible costs such as loss of pleasure or loss of companionship. These costs must be compared for both doing the intervention program and not doing the program but doing the alternatives. On the effect side, the analysis should include “hard” clinical outcomes: mor- tality, morbidity, residual functional ability, quality of life and utility of life, and the effect on future resources. These include the availability of services and future costs of health care and other services incurred by extending life. For example, it may be ﬁscally better to allow people to continue to smoke since this will reduce their life span and save money on end-of-life care for those people who die prematurely. The error made most often in performing cost-effectiveness analyses is the omission of consideration of opportunity costs that were referred to at the start of this chapter. If you pay for one therapeutic intervention you may not be able to pay for some other one. Cost-effectiveness analyses must include an analysis of these opportunity costs so that the reader can see what equivalent types of programs might need to be cut from the health-care budget in order to ﬁnance the new and presumably better intervention. Analyses that do not consider this issue are giving a biased view of the usefulness of the new program and keeping it out of the context of the most good for the greater society. The marginal or incremental gain for both the costs and effects should be cal- culated. This is the number of patients you must treat in order to achieve the desired effect in one additional patient. This is com- pared to the marginal cost of the better treatment to get a cost-effectiveness estimate. The marginal or incremental cost per life saved is then $180 000 [($2000 − $200) × 100 lives]. Also, the effects measured should include lives or years of life saved, improvement in level of function, or utility of the outcome for the patient. This works if the effects of the two interventions are equal or minimally different. For example, when compar- ing inpatient vein stripping to outpatient injection of varicose veins, the results shown in Table 31. Here the cost is so different that even if 13% of outpatients require additional hospitalization (and therefore we must pay for Cost-effectiveness analysis 355 Table 31.

The cost effective- ness of azithromycin for Chlamydia trachomatis infections in women. Another analysis compared doxycycline 100 mg twice a day for 7 days to azithromycin 1 g given as a one-time dose for the treatment of Chlamydia infec- tions in women. It found that some patients do not complete the full 7-day course for doxycycline and then need to be retreated, and can infect other people during that period of time (Table 31. The cost of azithromycin that would make the use of this drug cost-effective for all patients can then be calculated. In this case, the drug company making azithromycin actually lowered their price for the drug by over 50% based on that analysis, to a level that would make azithromycin more cost-effective. In a cost-effectiveness analysis the researcher seeks to determine how much more has to be paid in order to achieve a beneﬁt of preventing death or dis- ability time. The ﬁrst step in a cost-effectiveness analysis is to determine the difference in the beneﬁts or effects of the two treatment strategies or policies being compared. This is done using an Expected Values Decision Analysis as described in Chapter 30. It is possible that one of the tested strategies may have a relatively small beneﬁt and yet be overall more cost-effective than others therapies, which although only slightly less effective are very much more expensive. Next the difference in cost of the two treatment strategies or policies must be determined, to get the incremental or marginal cost. The cost-effectiveness is the ratio of the incremental cost to the incremental gain. The cost- effectiveness of B as compared to A is the difference in cost divided by the dif- ference in effects. Note that if the more effective treatment had also cost less, you should obviously use the more effective one unless it has other serious drawbacks such as serious known side effects. Calculate this only when the more effective treatment strat- egy or policy is also more costly. Are the conclusions unlikely to change with sensible changes in costs and outcomes?
