Health Insurance Models Comparison

Health Insurance Matrix

As you learn about health care delivery in the United States, it is necessary to understand the various models of health insurance to develop important foundational knowledge as you progress through the course and for your role as a future health care worker. The following matrix is designed to help you develop that knowledge and assist you in understanding how health care is financed and how health insurance influences patients and providers. Fill in the following matrix. Each box must contain responses between 50 and 100 words and use complete sentences.

(Health Insurance Models Comparison)

Model Describe the model How is the care paid or financed when this model is used? What is the structure behind this model? Is it a gatekeeper, open-access, or combination of both? What are the benefits for providers in using this model? What are the challenges for providers in using this model?
Health Maintenance Organization (HMO) . A type of health insurance plan that usually limits coverage to care from doctors who work for or contract with the HMO. It generally won’t cover out-of-network care except in an emergency. An HMO may require you to live or work in its service area to be eligible for coverage. HMOs often provide integrated care and focus on prevention and wellness.

 

Health maintenance organizations represent “pre-paid” or “capitated” insurance plans in which individuals or their employers pay a fixed monthly fee for services instead of a separate charge for each visit or service. The monthly fees remain the same, regardless of types or levels of services provided. Services are provided by physicians who are employed by, or under contract with, the HMO. You’ll select a Primary Care Physician who will be the first point of contact for your healthcare. You are encouraged to build a strong relationship with your PCP because they will connect you to specialists or other health care providers. Your PCP will be able to see the total picture of your overall health. With an HMO plan, your out-of-pocket medical costs and monthly premiums will generally be lower than with other types of plans. If you are someone who doesn’t see a lot of specialists or would like having your care coordinated through a PCP, then you might save more money with an HMO plan. Tight controls can make it more difficult to get specialized care

As an HMO member, you must choose a primary care physician (PCP). Your PCP provides your general medical care and must be consulted before you seek care from another physician or specialist. This screening process helps to reduce costs both for the HMO and for HMO members, but it can also lead to complications if your PCP doesn’t provide the referral you need

Preferred Provider Model . A Medicare PPO Plan is a type of Medicare Advantage Plan (Part C) offered by a private insurance company. In a PPO Plan, you pay less if you use doctors, hospitals, and other health care providers that belong to the plan’s network . You pay more if you use doctors, hospitals, and providers outside of the network Rather than prepaying for medical care, PPO members pay for services as they are rendered. The PPO sponsor (employer or insurance company) generally reimburses the member for the cost of the treatment, less any co-payment percentage. In some cases, the physician may submit the bill directly to the insurance company for payment. The insurer then pays the covered amount directly to the healthcare provider, and the member pays his or her co-payment amount. The price for each type of service is negotiated in advance by the healthcare providers and the PPO sponsor(s). Free choice of healthcare provider

PPO members are not required to seek care from PPO physicians. However, there is generally strong financial incentive to do so. For example, members may receive 90% reimbursement for care obtained from network physicians but only 60% for non-network treatment. In order to avoid paying an additional 30% out of their own pockets, most PPO members choose to receive their healthcare within the PPO network.

Out-of-pocket costs generally limited

Healthcare costs paid out of your own pocket (e.g., deductibles and co-payments) are limited. Typically, out-of-pocket costs for network care are limited to $1,200 for individuals and $2,100 for families. Out-of-pocket costs for non-network treatment are typically capped at $2,000 for individuals and $3,500 for families. And they have a free choice of healthcare provider.

More paperwork and expenses than HMOs

As a PPO member, you may have to fill out paperwork in order to be reimbursed for your medical treatment. Additionally, most PPOs have larger co-payment amounts than HMOs, and you may be required to meet a deductible. Less coverage for treatment provided by non-PPO physicians

As mentioned previously, there is a strong financial incentive to use PPO network physicians.

Point-of-Service Model A Point of Service (POS) plan is a type of managed healthcare system that combines characteristics of the HMO and the PPO. Like an HMO, you pay no deductible and usually only a minimal co-payment when you use a healthcare provider within your network. You also must choose a primary care physician who is responsible for all referrals within the POS network. If you choose to go outside the network for healthcare, POS coverage functions more like a PPO. No “gatekeeper” for non-network care

If you choose to go outside the POS network for treatment, you are free to see any doctor or specialist you choose without first consulting your primary care physician (PCP). Of course, you will pay substantially more out-of-pocket charges for non-network care.

POS coverage allows you to maximize your freedom of choice. Like a PPO, you can mix the types of care you receive. There is no minimal co-payment. Also when you choose to use network providers, there is generally no deductible. As well as no healthcare cost paid out of your own pocket Substantial co-payment for non-network care

As in a PPO, there is generally strong financial incentive to use POS network physicians. For example, your co-payment may be only $10 for care obtained from network physicians, but you could be responsible for up to 40% of the cost of treatment provided by non-network doctors. Thus, if your longtime family doctor is outside of the POS network, you may choose to continue seeing her, but it will cost you more.

Provider Sponsored Organization A Provider-Sponsored Organization (PSO) is a type of managed care plan that is operated by a group of doctors and hospitals that form a network of providers within which you must stay to receive coverage for your care. People with Medicare can choose to get their Medicare benefits through a PSO. PSO receives a fixed monthly payment to provide care for Medicare beneficiaries. PSOs may be developed as for-profit or not-for-profit entities of which at least 51 percent must be owned and governed by health care providers (physicians, hospitals or allied health professionals). PSOs may be organized as either public or private entities The gatekeeper would be Medicare in the United States can be defined as ‘ A group of doctors, hospitals, and other health care providers that agree to give health care to Medicare beneficiaries for a set amount of money from Medicare every month. This type of managed care plan is run by the doctors and providers themselves, and not by an insurance company
High Deductible Health Plans and Savings Options A health savings account (HSA) is a tax-advantaged medical savings account available to taxpayers in the United States who are enrolled in a high-deductible health plan (HDHP). The funds contributed to an account are not subject to federal income tax at the time of deposit. You have the freedom to see any health care provider, including specialists, without a referral, although you will save money if you see in-network providers. This is especially important since instead of a copay, you will be paying the full cost of a doctor’s visit or service until you satisfy your deductible Others can contribute to your HSA. Contributions can come from various sources, including you, your employer, a relative and anyone else who wants to add to your HSA. High deductible plans also allow you to meet health plan stipulations that your community may have. By having yourself and your family covered with health insurance, you can be in compliance with specific laws that require insurance coverage. You have high deductible requirement. Even though you are paying less in premiums each month, it can be difficult – even with money in an HSA – to come up with the cash to meet a high deductible.

You have unexpected healthcare costs. Your healthcare costs could exceed what you had planned for, and you may not have enough money saved in your HSA to cover expenses.

Social Media Use In Health Care

Prepare A 2-Page Interprofessional Staff Update On HIPAA And Appropriate Social Media Use In Health Care

Introduction

Health professionals today are increasingly accountable for the use of protected health information (PHI). Various government and regulatory agencies promote and support privacy and security through a variety of activities. Examples include:

  • Meaningful use of electronic health records (EHR).
  • Provision of EHR incentive programs through Medicare and Medicaid.
  • Enforcement of the Health Insurance Portability and Accountability Act (HIPAA) rules.
  • Release of educational resources and tools to help providers and hospitals address privacy, security, and confidentiality risks in their practices.

Technological advances, such as the use of social media platforms and applications for patient progress tracking and communication, have provided more access to health information and improved communication between care providers and patients.

At the same time, advances such as these have resulted in more risk for protecting PHI. Nurses typically receive annual training on protecting patient information in their everyday practice. This training usually emphasizes privacy, security, and confidentiality best practices such as:

  • Keeping passwords secure.
  • Logging out of public computers.
  • Sharing patient information only with those directly providing care or who have been granted permission to receive this information.

Today, one of the major risks associated with privacy and confidentiality of patient identity and data relates to social media. Many nurses and other health care providers place themselves at risk when they use social media or other electronic communication systems inappropriately. For example, a Texas nurse was recently terminated for posting patient vaccination information on Facebook. In another case, a New York nurse was terminated for posting an insensitive emergency department photo on her Instagram account.

Health care providers today must develop their skills in mitigating risks to their patients and themselves related to patient information. At the same time, they need to be able distinguish between effective and ineffective uses of social media in health care.

This assessment will require you to develop a staff update for the interprofessional team to encourage team members to protect the privacy, confidentiality, and security of patient information.

Demonstration of Proficiency

By successfully completing this assessment, you will demonstrate your proficiency in the course competencies through the following assessment scoring guide criteria:

  • Competency 1: Describe nurses’ and the interdisciplinary team’s role in informatics with a focus on electronic health information and patient care technology to support decision making.
    • Describe the security, privacy, and confidentially laws related to protecting sensitive electronic health information that govern the interdisciplinary team.
    • Explain the importance of interdisciplinary collaboration to safeguard sensitive electronic health information.
  • Competency 2: Implement evidence-based strategies to effectively manage protected health information.
    • Identify evidence-based approaches to mitigate risks to patients and health care staff related to sensitive electronic health information.
    • Develop a professional, effective staff update that educates interprofessional team members about protecting the security, privacy, and confidentiality of patient data, particularly as it pertains to social media usage.
  • Competency 5: Apply professional, scholarly communication to facilitate use of health information and patient care technologies.
    • Follow APA style and formatting guidelines for citations and references.
    • Create a clear, concise, well-organized, and professional staff update that is generally free from errors in grammar, punctuation, and spelling.

Preparation

(Interprofessional Staff Update On HIPAA)

To successfully prepare to complete this assessment, complete the following:

  • Review the infographics on protecting PHI provided in the resources for this assessment, or find other infographics to review. These infographics serve as examples of how to succinctly summarize evidence-based information.
    • Analyze these infographics, and distill them into five or six principles of what makes them effective. As you design your interprofessional staff update, apply these principles. Note: In a staff update, you will not have all the images and graphics that an infographic might contain. Instead, focus your analysis on what makes the messaging effective.
  • Select from any of the following options, or a combination of options, the focus of your interprofessional staff update:
    • Social media best practices.
    • What not to do: Social media.
    • Social media risks to patient information.
    • Steps to take if a breach occurs.
  • Conduct independent research on the topic you have selected in addition to reviewing the suggested resources for this assessment. This information will serve as the source(s) of the information contained in your interprofessional staff update. Consult the BSN Program Library Research Guide for help in identifying scholarly and/or authoritative sources.

Instructions

(Interprofessional Staff Update On HIPAA)

In this assessment, assume you are a nurse in an acute care, community, school, nursing home, or other health care setting. Before your shift begins, you scroll through Facebook and notice that a coworker has posted a photo of herself and a patient on Facebook. The post states, “I am so happy Jane is feeling better. She is just the best patient I’ve ever had, and I am excited that she is on the road to recovery.”

You have recently completed your annual continuing education requirements at work and realize this is a breach of your organization’s social media policy. Your organization requires employees to immediately report such breaches to the privacy officer to ensure the post is removed immediately and that the nurse responsible receives appropriate corrective action.

You follow appropriate organizational protocols and report the breach to the privacy officer. The privacy officer takes swift action to remove the post. Due to the severity of the breach, the organization terminates the nurse.

Based on this incident’s severity, your organization has established a task force with two main goals:

  • Educate staff on HIPAA and appropriate social media use in health care.
  • Prevent confidentiality, security, and privacy breaches.

The task force has been charged with creating a series of interprofessional staff updates on the following topics:

  • Social media best practices.
  • What not to do: Social media.
  • Social media risks to patient information.
  • Steps to take if a breach occurs.

You are asked to select one of the topics, or a combination of several topics, and create the content for a staff update containing a maximum of two content pages. When distributed to interprofessional team members, the update will consist of one double-sided page.

The task force has asked team members assigned to the topics to include the following content in their updates in addition to content on their selected topic(s):

  • What is protected health information (PHI)?
    • Be sure to include essential HIPAA information.
  • What are privacy, security, and confidentiality?
    • Define and provide examples of privacy, security, and confidentiality concerns related to the use of the technology in health care.
    • Explain the importance of interdisciplinary collaboration to safeguard sensitive electronic health information.
  • What evidence relating to social media usage and PHI do interprofessional team members need to be aware of? For example:
    • How many nurses have been terminated for inappropriate social media usage in the United States?
    • What types of sanctions have health care organizations imposed on interdisciplinary team members who have violated social media policies?
    • What have been the financial penalties assessed against health care organizations for inappropriate social media usage?
    • What evidence-based strategies have health care organizations employed to prevent or reduce confidentiality, privacy, and security breaches, particularly related to social media usage?
Notes
  • Your staff update is limited to two double-spaced content pages. Be selective about the content you choose to include in your update so that you are able to meet the page length requirement. Include need-to-know information. Leave out nice-to-know information.
  • Many times people do not read staff updates, do not read them carefully, or do not read them to the end. Ensure your staff update piques staff members’ interest, highlights key points, and is easy to read. Avoid overcrowding the update with too much content.
  • Also supply a separate reference page that includes 2–3 peer-reviewed and 1–2 non-peer-reviewed resources (for a total of 3–5 resources) to support the staff update content.
Additional Requirements
  • Written communication: Ensure the staff update is free from errors that detract from the overall message.
  • Submission length: Maximum of two double-spaced content pages.
  • Font and font size: Use Times New Roman, 12-point.
  • Citations and references: Provide a separate reference page that includes 2–3 current, peer-reviewed and 1–2 current, non-peer-reviewed in-text citations and references (total of 3–5 resources) that support the staff update’s content. Current mean no older than 5 years.
  • APA format: Be sure your citations and references adhere to APA format. Consult the APA Style and Format page for an APA refresher.

Based on your findings in which years hospitals had better performance? Please write a short paragraph and describe your findings.

The hospitals had better performance in 2012 compared to 2011. The mean number of hospital beds in 2012 was slightly higher than the mean number of hospital beds in 2011. In terms of revenue, the mean revenue in 2012 was higher than the mean revenue in 2011. The total cost in 2011 was also higher than the total cost in 2012. For these variables, the p. Value is less than 0.05 hence the null hypothesis is not rejected at 95% confidence interval. This implies that the means between the two groups are not different.

solution 

Comparison of Hospital Performance: 2011 vs. 2012

Based on the descriptive statistics provided in the dataset, hospitals performed slightly better in 2012 than in 2011. The mean number of hospital beds in 2012 (376.8) was marginally higher than in 2011 (376.6), suggesting that hospitals maintained or slightly increased their capacity. Additionally, the mean number of paid employees rose notably from 1,237 in 2011 to 1,491 in 2012, reflecting an increase in staffing, which could contribute to improved care delivery and operational efficiency.

Moreover, total hospital revenues increased slightly in 2012, rising from an average of $228.7 million to $229.9 million, while total hospital costs slightly decreased from $216.9 million to $214.7 million. This favorable shift in financial indicators suggests improved cost management and potentially higher profitability. Available Medicare and Medicaid days also increased, along with the number of discharges, indicating higher patient throughput and greater service utilization.

Despite all p-values being less than 0.05—specifically noted as less than 2.2e-16—this statistical significance does not necessarily imply a large or meaningful practical difference. Rather, it shows that the observed differences in means between 2011 and 2012 are statistically significant due to the large sample size. Therefore, even slight changes can appear statistically significant.

In conclusion, the descriptive data suggest slightly improved hospital performance in 2012, characterized by increased revenue, more paid staff, and higher service output, despite minimal differences in some variables.

Smoking and Lung Cancer Epidemiology

Smoking and Lung Cancer Epidemiology

(Smoking and Lung Cancer Epidemiology)

Epidemiology Worksheet

IHP 330 Module Two Worksheet Measuring Disease

A causal relationship between cigarette smoking and lung cancer was first suspected in the 1920s on the basis of clinical observations. To test this apparent association, numerous epidemiologic studies were undertaken between 1930 and 1960. Two studies were conducted by Richard Doll and Austin Bradford Hill in Great Britain. The first was a case-control study begun in 1947 comparing the smoking habits of lung cancer patients with the smoking habits of other patients. The second was a cohort study begun in 1951 recording causes of death among British physicians in relation to smoking habits. This case study deals first with the case-control study, then with the cohort study.

Data for the case-control study were obtained from hospitalized patients in London and vicinity over a four-year period (April 1948 – February 1952). Initially, 20 hospitals, and later more, were asked to notify the investigators of all patients admitted with a new diagnosis of lung cancer. These patients were then interviewed concerning smoking habits, as were controls selected from patients with other disorders (primarily nonmalignant) who were hospitalized in the same hospitals at the same time. Data for the cohort study were obtained from the population of all physicians listed in the British Medical Register who resided in England and Wales as of October 1951. Information about present and past smoking habits was obtained by questionnaire. Information about lung cancer came from death certificates and other mortality data recorded during ensuing years.

Over 1700 patients with lung cancer, all under age 75 were eligible for the case-control study. About 15% of these persons were not interviewed because of death, discharge, severity of illness, or inability to speak English. An additional group of patients were interviewed by later excluded when initial lung cancer diagnosed proved mistaken. The final study group included 1,465 cases (1,357 males and 108 females). The following table shows the relationship between cigarette smoking and lung cancer among male cases and controls:

Table 1

Cases Controls
Cigarette Smoker 1,350 1,296
Nonsmoker 7 61
Total 1,357 1,357

 

1. Accurately calculate the proportion of cases that smoked. Be sure to show your calculations.

2. Accurately calculate the proportion of controls that smoked. Be sure to show your calculations.

3. Accurately calculate the odds ratio, with the correct equation. What do you infer from the odds ratio about the relationship between smoking and lung cancer?

Table 2 shows the frequency distribution of male cases and controls by average number of cigarettes smoked per day.

15–24 445 408
25+ 340 182
All smokers 1350 1296
Total 1357 1357

4. Accurately calculate the odds ratios by category of daily cigarette consumption, comparing each category to nonsmokers. Be sure to show your calculations.

5. Interpret these results, and describe the trends or patterns you see in the data.

Part 2: The Cohort Study

Data for the cohort study were obtained from the population of all physicians listed in the British Medical Register who resided in England and Wales as of October 1951. Questionnaires were mailed in October 1951 to 59,600 physicians. The questionnaire asked the physicians to classify themselves into one of three categories: 1) current smoker, 2) ex-smoker, or 3) nonsmoker. Smokers and ex-smokers were asked the amount they smoked, their method of smoking, the age they started to smoke, and, if they had stopped smoking, how long it had been since they last smoked. Nonsmokers were defined as persons who had never consistently smoked as much as one cigarette day for as long as one year. Physicians were also asked whether or not they had a diagnosis of lung cancer. Usable responses to the questionnaires were received from 40,637 (68%) physicians, of whom 34,445 were males and 6,192 were females. The next section of this case study is limited to the analysis of male physician respondents, 35 years of age or older.

The occurrence of lung cancer in physicians responding to the questionnaire was documented over a 10-year period (November 1951 through October 1961) from death certificates filed with the Registrar General of the United Kingdom and from lists of physician deaths provided by the British Medical Association. All certificates indicating that the decedent was a physician were abstracted. For each death attributed to lung cancer, medical records were reviewed to confirm the diagnosis.

Diagnoses of lung cancer were based on the best evidence available; about 70% were from biopsy, autopsy, or sputum cytology (combined with bronchoscopy or X-ray evidence); 29% were from cytology, bronchoscopy, or X-ray alone; and only 1% were from just case history, physical examination, or death certificate. In total, there were 355 cases of lung cancer during this 10-year time period, with 255 newly diagnosed cases of lung cancer.

Of 4,597 deaths in the cohort over the 10-year period, 157 were reported to have been caused by lung cancer; in 4 of the 157 cases this diagnosis could not be documented, leaving 153 confirmed deaths from lung cancer.

The following table shows numbers of lung cancer deaths by daily number of cigarettes smoked at the time of the 1951 questionnaire (for male physicians who were nonsmokers and current smokers only). Person-years of observation (“person-years at risk”) are given for each smoking category. The number of cigarettes smoked was available for 136 of the persons who died from lung cancer.Table 3: Number and rate (per 100,000 person-years) of lung cancer deaths by number of cigarettes smoked per day, Doll and Hill physician cohort study, Great Britain, 1951–1961.

15–24 54 38,900
25+ 57 25,100
All smokers 133 102,600
Total 136 145,400

6. Accurately calculates the lung cancer mortality rates for each smoking category. Be sure to show your calculations.

7. Describe the trends or patterns you see in the data about mortality, and explain what the trends or patterns mean.

8. Accurately calculate the incidence for lung cancer during the 10 year time period. Be sure to show your calculations.

9. Accurately calculate the prevalence for lung cancer during this 10 year time period. Be sure to show your calculations.
