I thought I’d share my regulatory notes for the BCPS Exam 2013. There were quite a bit of regulatory questions last year. You know the type, “What does the whatever committee for whatever ensure?” Um, ‘scuse me?
We should know by now what The Joint Commission is. Organized in the 1950′s, it meshes with the Medicare Act in the 1960′s. In other words, to be eligible for Medicare/Medicaid, you must be accredited by TJC. In the late 1980′s, TJC shifted its focus to actual performance. An independent, not-for-profit organization, The Joint Commission accredits and certifies more than 20,000 health care organizations and programs in the United States. Joint Commission accreditation and certification is recognized nationwide as a symbol of quality that reflects an organization’s commitment to meeting certain performance standards.
National Committee for Quality Assurance (1990) – how health plans are regulated and accreditation of health plans. The National Committee for Quality Assurance is a private, 501(c)(3) not-for-profit organization dedicated to improving health care quality. Since its founding in 1990, NCQA has been a central figure in driving improvement throughout the health care system, helping to elevate the issue of health care quality to the top of the national agenda.
- Healthcare Effectiveness and Data Information Set (HEDIS) - HEDIS® (The Healthcare Effectiveness Data and Information Set) is the gold standard in health care performance measurement, used by more than 90 percent of the nation’s health plans and many leading employers and regulators. HEDIS is a set of standardized measures that specifies how organizations collect, audit and report performance information across the most pressing clinical areas, as well as important dimensions of customer satisfaction and patient experience.
The National Quality Forum (NQF) is a nonprofit, nonpartisan, public service organization committed to this transformation.
NQF reviews, endorses, and recommends use of standardized healthcare performance measures. Performance measures, also called quality measures, are essential tools used to evaluate how well healthcare services are being delivered. NQF’s endorsed measures are often invisible at the clinical bedside but quietly influence the care delivered to millions of patients every day. Measures:
- Make our healthcare system more information rich
- Point to actions physicians, other clinicians, and organizations can take to make healthcare safe and equitable
- Enhance transparency in healthcare
- Ensure accountability of healthcare providers
- Generate data that helps consumers make informed choices about their care
Working with members and the public, NQF also helps define our national healthcare improvement ‘to-do’ list, and encourages action and collaboration to accomplish quality improvement goals.
Institute of Medicine’s “Crossing the Quality Chasm” - This report from the committee on the Quality of Health Care in America makes an urgent call for fundamental change to close the quality gap, recommends a redesign of the American health care system, and provides overarching principles for specific direction for policymakers, health care leaders, clinicians, regulators, purchasers, and others.

Hospital Consumer Assessment of Healthcare Providers and Systems – HCAHPS - assessment of quality of care from a patient’s perspective.
Pharmacy Quality Alliance To improve the quality of medication management and use across healthcare settings with the goal of improving patients’ health through a collaborative process to develop and implement performance measures and recognize examples of exceptional pharmacy quality.
Electronic Health Record (EHR) Incentive program - provides financial incentives for the “meaningful use” of certified EHR technology to improve patient care. Meaningful Use = Incentives
Patient Protection and Affordable Care Act - (Obamacare) (Affordable Care Act) The ACA aims to increase the quality and affordability of health insurance, lower the uninsured rate by expanding public and private insurance coverage, and reduce the costs of healthcare for individuals and the government. It provides a number of mechanisms—including mandates, subsidies, and insurance exchanges—to increase coverage and affordability. The law also requires insurance companies to cover all applicants within new minimum standards and offer the same rates regardless of pre-existing conditions or sex. Additional reforms aim to reduce costs and improve healthcare outcomes by shifting the system towards quality over quantity through increased competition, regulation, and incentives to streamline the delivery of healthcare. The Congressional Budget Office projected that the ACA will lower both future deficits and Medicare spending.

Medicare Hospital Inpatient Value-Based Purchasing Benchmark – 95th percentile -
The HVBP program is designed to promote better clinical outcomes for hospital patients, as well as improve their experience of care during hospital stays. Specifically, Hospital VBP seeks to encourage hospitals to improve the quality and safety of care that Medicare beneficiaries and all patients receive during acute-care inpatient stays by:
- eliminating or reducing the occurrence of adverse events (healthcare errors resulting in patient harm)
- adopting evidence-based care standards and protocols that result in the best outcomes for the most patients
- re-engineering hospital processes that improve patients’ experience of care
Fiscal Years – Federal is Oct through Sept
For FY 2013, the performance period spans three quarters from July 1, 2011 – March 31, 2012.
Achievement Threshold - To measure improvement, CMS will assess how much each hospital’s performance during the performance period changes from its own baseline period performance. CMS will award points to hospitals based on their level of improvement between that baseline score and the benchmark score. CMS will only award points for improvement if a hospital’s performance during the performance period is greater than its performance during the baseline period. To measure achievement, CMS will assess how much each hospital’s performance during the performance period differs from the performance of all other hospitals during the baseline period. CMS will only award achievement points if a hospital’s performance during the performance period exceeds the 50th percentile of all hospitals’ performance during the baseline period. The 50th percentile is defined by CMS as the “achievement threshold.”
Scoring Based on Achievement
- 0 to 10 points scored relative to the achievement threshold and the benchmark
- Thresholds and benchmarks determined from national hospital performance in the prior year
Scoring Based on Improvement
- 0 to 9 points for improvement based on a hospital improving its score on the measure from its prior year performance
Each domain of measures is initially scored separately, weighting each measure within that domain equally. All domain scores are then aggregated and combined, along with the HCAHPS, with the potential for different weighting by domain.
CMS then weighs and combines each hospital’s domain scores to determine the hospital’s Total Performance Score:
Total Earned Points = Sum of points earned across all reported measures within each domain
Total Possible Points = Number of measures reported by hospital x 10
Total Performance Score = Total Earned Points / Total Possible Points x 100
Finally, CMS translates each hospital’s Total Performance Score into an incentive payment using an exchange function.

Tracer methodology - TJC – using pt’s medical record as a road map to move through the organization. The Joint Commission’s on-site survey process includes tracer methodology. Tracer methodology is an evaluation method in which surveyors select a patient, resident or client and use that individual’s record as a roadmap to move through an organization to assess and evaluate the organization’s compliance with selected standards and the organization’s systems of providing care and services. Surveyors retrace the specific care processes that an individual experienced by observing and talking to staff in areas that the individual received care. As surveyors follow the course of a patient’s, resident’s or client’s treatment, they assess the health care organization’s compliance with Joint Commission standards. They conduct this compliance assessment as they review the organization’s systems for delivering safe, quality health care.
- Before a procedure, label medicines that are not labeled. For example, medicines in syringes, cups and basins. Do this in the area where medicines and supplies are set up.
- Take extra care with patients who take medicines to thin their blood.
- Record and pass along correct information about a patient’s medicines. Find out what medicines the patient is taking. Compare those medicines to new medicines given to the patient. Make sure the patient knows which medicines to take when they are at home. Tell the patient it is important to bring their up-to-date list of medicines every time they visit a doctor.
- Improve staff communication. Get important test results to the right staff person on time.
- Identify patients correctly. Use at least two ways to identify patients. For example, use the patient’s name and date of birth. This is done to make sure that each patient gets the correct medicine and treatment.
- Hand hygiene and contact precautions
- Anticoagulation – pt education
Durham-Humphrey Amendment of 1951 – Explicitly defined two specific categories for medications, legend (prescription) and over-the-counter (OTC). This amendment was co-sponsored by former vice president and senator Hubert H. Humphrey Jr., who was a pharmacist in South Dakota before beginning his political career. The other sponsor of this amendment was Carl Durham, a pharmacist representing North Carolina in the House of Representatives.
The bill requires any drug that is habit-forming or potentially harmful to be dispensed under the supervision of a health practitioner as a prescription drug and must carry the statement, “Caution: Federal law prohibits dispensing without a prescription.”
Until this law, there was no requirement that any drug be labeled for sale by prescription only. The amendment defined prescription drugs as those unsafe for self-medication and which should therefore be used only under a doctor’s supervision.
Legend drugs can only be dispensed with direct medical supervision whereas OTC drugs can be purchased and used without a prescription. This law also legalized verbal transmission of prescriptions and provided for the legal right of a pharmacist to refill prescriptions as indicated in a provider’s initial prescription.
Drug Importation Act of 1848 - requires U.S. Customs inspection to stop entry of adulterated drugs from overseas. Note the strict construction of the Federal Government’s involvement in interstate commerce.
The Biologics Control Act of 1902 - is passed to insure purity and safety of serums, vaccines, and similar products used to prevent or treat diseases in humans. In 1970, regulation of biologics is transferred to the FDA.
Pure Food and Drug Act of 1906 - prohibits interstate commerce in misbranded and adulterated foods, drinks and drugs. The Department of Agriculture is authorized to seize unsafe substances and prosecute violators. Note that in the good old days, “misbranded” meant that the label did not accurately describe the contents, and “adulterated” meant that the claimed ingredients had been diluted, (as flour might be diluted by pea meal). The intent of the act was to provide penalties for consumer fraud and to prevent injury and death from poisons.
Food, Drug, and Cosmetic Act of 1938 - replaces the 1906 act. It contains new provisions extending control to cosmetics and therapeutic devices; requiring new drugs to be shown safe before marketing–starting a new system of drug regulation; eliminating the pesky Sherley Amendment requirement that intent to defraud must be proved in drug misbranding cases; providing that safe tolerances be set for unavoidable poisonous substances; authorizing factory inspections; and adding the remedy of court injunctions to the previous penalties of seizures and prosecutions.
Kefauver-Harris Amendments of 1962 - to ensure greater drug safety. For the first time, drug manufacturers are required to prove to FDA the effectiveness of their products before marketing them. Demonstrate efficacy and safety. Informed consent for research participants. FDA regulates advertising of prescription drugs and establish good manufacturing practices.
Orphan Drug Act of 1983 - enables FDA to speed up and streamline approval and marketing of drugs needed for treating rare diseases, which otherwise would not be profitable. (pt population <200,000)
Prescription Drug User Fee Act (PDUFA) - requires drug and biologics manufacturers to pay fees for drug and biologics applications and supplements. In addition, these firms must pay an annual establishment fee and annual product fees. FDA will use these funds to hire more reviewers to assess applications. Renewed every five years ’92, ’97, ’02, ’07, ’12, etc…
Dietary Supplemental Health and Education Act of 1994 - establishes specific labeling requirements, provides a regulatory framework, and authorizes FDA to promulgate good manufacturing practice regulations for “dietary supplements” and “dietary ingredients” and classifies them as food. The act also establishes a commission to recommend how to regulate label claims.
FDA Safety and Innovation Act (FDASIA) or PDUFA 2012 – drug shortage – drug manufacturers must notify FDA at least 6 months prior to d/c or interruption of certain meds or as soon as practicable.

Risk Evaluation and Mitigation Systems (REMS) – meds that the FDA didn’t approve to put on the market balancing risk/benefit w/harm.
FDA Amendment Act of 2007 (PDUFA IV) - The FDA requested and received fee increases to cover increased reviewer workload and expanded post-marketing safety initiatives, as well as the authority to apply user fees to the monitoring of direct-to-consumer drug advertising.President Bush signed the reauthorization of PDUFA into law on 27 September 2007.
