It takes twice as long to perform Service C, so the doctors decided Service C should count as two services for the purpose of calculating workload. If Service C counts twice as much as Service A or Service B, then the physician who provides the most services was Doctor The physicians at Sunset Shore Clinic reported the following statistics last Tuesday.

Accepted Answer

The answer of It takes twice as long to perform...

Question 2

Your facility conducted a study of patient satisfaction, but you question the reliability of the questionnaire you used. The high degree of patient satisfaction expressed on the questionnaire just doesn't match the large number of complaints you have been receiving. You decide to try switching to an investigative strategy that will give you an immediate opportunity to review patient responses and correct errors. You have decided to use

Accepted Answer

Interviews allow for immediate interaction with patients, enabling clarification and correction of any misunderstandings or errors in real-time, which can provide more reliable data compared to questionnaires.

Question 3

Your administrator is concerned about the snuff study (see previous question #88). The administrator would like to consider using a case control study model rather than the prospective one you are planning. One of the biggest reasons the administrator is promoting the case control model is because case control is

Accepted Answer

Case control studies are generally less expensive than prospective studies because they often use existing records and data, rather than following subjects over time.

Question 4

If population size (N) = 1200 and the proportion of subjects needed (p) = 0.5 and the acceptable amount of error (B) = 0.05, then sample size (n) =

Question 5

You and your colleague are designing a study to try to determine the ideal mean cost for discretionary service. You will market your service to a very large population. Your colleague thinks you will get the best data if you take lots of small samples. You think the data will be neat reliable if you take one or two very large samples.

Accepted Answer

Taking one or two very large samples will yield more reliable results because it will decrease the sampling error and provide a better representation of the population. This is also more efficient and cost-effective than taking multiple small samples. However, it is important to ensure that the samples are selected randomly and are large enough to accurately represent the population.

Question 6

The American Health Information Management Association conducted a study on job stress and job satisfaction in HIM professionals with,more than 5 years of experience. The data they collected is displayed below. The next five questions will be based on this study and the data collected for it.  The researchers at AHIMA started by assuming there was no relationship between job stress a job satisfaction. This statement is generally called the

Accepted Answer

The assumption that there is no relationship between job stress and job satisfaction is a null hypothesis, which is assumed until proven otherwise through statistical analysis.

Question 7

What process assists a health care facility in continuously looking at the ways that problems develop and seeking ways to prevent problems from happening in the future?

Accepted Answer

Performance improvement, also known as quality improvement, is a process used by health care facilities to continuously assess and analyze their practices and outcomes with the goal of identifying areas for improvement and preventing future problems. This process involves developing and implementing strategies to enhance the quality of care and outcomes for patients. While risk management, quality control, and utilization management are important components of overall patient care, they do not specifically focus on continuous improvement and prevention of problems in the same way that performance improvement does.

Question 8

The people of Treasure Island Beach have been struck with a rash that seems to be infecting almost everyone in town. The staff of the hospital is working to design a study of this mysteri' disease. They decide to do a cross-sectional study because cross-sectional or prevalence studies are known for

Accepted Answer

Cross-sectional studies are designed to gather data on a population at a specific point in time. By collecting data on the prevalence or incidence of a disease, researchers can identify risk factors and characteristics associated with the disease. This information can be used to design further research studies, improve public health interventions, and inform clinical practice. However, cross-sectional studies are not designed to establish cause-and-effect relationships or test the effectiveness of specific treatments.

Question 9

A study found that liver cancer rates per 100,000 males among cigarette smokers and nonsmokers in a major U.S. city were 48.0 and 25.4, respectively. The relative risk of developing liver cancer for male smokers compared to nonsmokers is

Accepted Answer

Relative risk (RR) = incidence rate in exposed group/incidence rate in unexposed group.

Here, RR = 48.0/25.4 = 1.89.

Therefore, the relative risk of developing liver cancer for male smokers compared to nonsmokers is 1.89, or choice A.

Question 10

A major disadvantage of cross-sectional studies is that

Accepted Answer

Cross-sectional studies only provide information at one point in time and do not follow individuals over time. Therefore, it is not possible to determine the timing of exposure and disease.

Question 13

You are planning a prospective study to try to prove a cause and effect relationship between dipping snuff and throat cancer. First, you identify subjects who regularly dip snuff and who are free of any signs of throat cancer. Next, you need to identify subjects who

Accepted Answer

In a prospective study, you need a control group that does not have the exposure (dipping snuff) and is free of the outcome (throat cancer) to compare against the exposed group.

Question 14

Investigator A claims his results are statistically significant at the 10% level. Investigator B argues that significance should be announced only if the results are statistically significant at the 5% level. From this we can conclude

Accepted Answer

It will be more difficult for investigator A to reject statistical null hypotheses if he always works at the 10% level compared with investigator B who works at the 5% level. This is because the 5% level is a more stringent criterion for statistical significance than the 10% level. As a result, investigator A will be less likely to find statistically significant results when working at the 5% level than when working at the 10% level.

Question 15

John Parker surveyed members of AHIMA's student COP regarding the relationship betwed clinical experiences and job opportunities. All respondents were seniors in HIA programs ai each one expected to graduate and take the national exam within the next 6 months. Fifteen of tie eighteen respondents indicated at least one clinical rotation had resulted in a job offer. Based c this information, Parker expects to be offered a job during senior clinical rotations. John is basin this expectation on

Accepted Answer

John is using inductive reasoning by drawing a general conclusion based on a specific observation or pattern. He has observed that most of the respondents who had a clinical rotation received a job offer, therefore he expects to receive a job offer as well during his senior clinical rotation. It is not a scientific inquiry or empiricism as there is no experimentation or observation of natural phenomena. It is also not deductive reasoning as he is not starting with a general premise and reasoning to a specific conclusion.

Question 16

There were some HIM professionals who refused to participate in the job stress/job satisfaction study. This is of great concern to the AHIMA researchers, who worry about the introduction of

Accepted Answer

The refusal by some HIM professionals to participate in the study introduces nonresponse bias, which can lead to inaccurate conclusions as the nonresponses may hold different opinions and perspectives from the respondents.

Question 17

Question 18

After the researchers see the number of subjects they will have to interview, they re­examine the criteria. The researchers could decrease the number of subjects while having the least impact the reliability of the study by

Accepted Answer

By decreasing p (the level of significance or probability of a type I error) or increasing B (the effect size), the researchers may be able to decrease the number of subjects without significantly impacting the reliability of the study. Decreasing p means that the study is more conservative in rejecting the null hypothesis, which can help to prevent false positives. Increasing B means that the difference between the groups being studied is larger, making it easier to detect statistically significant results with fewer subjects. Both options can help to maintain the integrity of the study while reducing the sample size.

Question 19

You are conducting a patient satisfaction survey in your outpatient clinic using interviewers administer a questionnaire. Because you typically see about 300 people per day in the clinic, decide to have the interviewers administer the questionnaire on every tenth patient. You using

Accepted Answer

The method being used is systematic sampling, as the interviewer is sampling every tenth patient in a systematic way. This is a more efficient way to sample than convenience sampling, as it ensures that every member of the population has an equal chance of being included in the sample. Stratified sampling involves dividing the population into subgroups and sampling from each subgroup, which is not being done in this scenario. Variable sampling involves adjusting the sample size based on certain characteristics, which is also not being done in this scenario.

Question 20

The researchers at AHIMA had professionals with 5 or more years HIM experience rate their stress on a scale of 1 to 5, as shown in the chart above. Job satisfaction and job stress are both continuous variables. If the AHIMA researchers want to assess both the direction and degree of the relationship between these two continuous variables, they may choose to compute the
