Healthgrades Mortality & Complications Outcomes Methodology 3 • • •

Introduction To help consumers evaluate and compare hospital performance for care provided during a hospital stay for specific conditions or procedures, Healthgrades analyzed clinical outcomes data for virtually every hospital in the country. Analyses included Medicare-patient care records for nearly 4,500 short-term, acute care hospitals nationwide, assessing hospital performance relative to each of 32 common conditions and procedures (cohorts), plus two cohorts using all-payer data. The Healthgrades methodology uses multivariate logistic regression to risk adjust for patient demographic and clinical risk factors that influence patient outcomes in significant and systematic ways.

The purpose of risk adjustment is to obtain fair statistical comparisons of mortality and complication rates between hospitals while accounting for differences in underlying risk factors observed in the data among disparate populations or groups. Significant differences in demographic and clinical risk factors are found among patients treated in different hospitals; thus, it is necessary to make accurate and valid comparisons of clinical outcomes with a methodology using risk-adjustment techniques. Risk factors may include age, gender, specific procedure performed, and comorbid conditions, such as hypertension and diabetes.

Individual risk models are constructed and tailored for each of the 34 conditions or procedures relative to each specific outcome. Model clinical outcomes reflect clinical-based measures of patient status during and after care (during the episode of care in a hospital stay) and include: in-hospital complications, in-hospital mortality, and 30-day post-admission mortality. In cases where Medicare data do not adequately represent the population with a specific condition or having a specific procedure, such as appendectomy and bariatric surgery, Healthgrades evaluated hospitals using all-payer data from 15 states and the District of Columbia.

Data Acquisition Healthgrades used the following data sources in the analysis of hospital patient records:

• Medicare inpatient data from the Medicare Provider Analysis and Review (MedPAR) file purchased from the Centers for Medicare and Medicaid Services (CMS) for years 2015 through 2017. The MedPAR data were selected for several reasons:

• Almost every hospital in the country is included in the database, with the exception of military and Veterans Administration hospitals.

• Accuracy is regulated. Hospitals are required by law to submit complete and accurate information for fee-for-service Medicare patient hospital care with substantial penalties for those that report inaccurate or incomplete data.

• The Medicare population represents a majority of the patients for virtually all of the clinical categories studied.

• Inpatient data for the appendectomy and bariatric surgery cohorts were provided by 15 states and the District of Columbia that provide all-payer state data.

• Colorado • Maryland • Oregon • Virginia* • District of Columbia • Nevada* • Pennsylvania • Washington* • Florida • New Jersey • Rhode Island* • West Virginia • Iowa • New York • Texas • Wisconsin

*See Appendix F. All-payer States Citations and Disclaimers


• Since the appendectomy and bariatric surgery cohorts include very few patients older than 65 years of age, all-payer state data were used to rate hospitals in those states where state data were available. Consequently, appendectomy and bariatric surgery cohorts were based exclusively on state data from years 2014 through 2016 (one year behind MedPAR data years).

Healthgrades conducted a series of data quality checks to preserve the integrity of the analyses. Based on the applied integrity checks, up to 50% of patient records were excluded from the MedPAR 2015-2017 and all-payer 2014-2016 analysis, depending on the cohort. Patient records were identified for exclusion because, for example, they were determined to be miscoded or were otherwise inappropriate for inclusion in the data sets used for analyses.

Examples of Healthgrades standard rules used to exclude patient records are:

• Patients under the age of 65.

• Patients who left the hospital against medical advice or who were transferred to another acute care hospital.

• Patients discharged alive with a length of stay that is inconsistent with the reason for admission (e.g., a patient discharged alive with a one-day length of stay for valve surgery would be excluded because this procedure requires several days for in-hospital recovery).

• Patients who were still in the hospital when the claim was filed.

• Patients with an invalid gender (e.g., a prostatectomy related to a female patient).

• Patients with an invalid age.

• Patients who have had any organ transplant.

• Patients in medical cohorts who were discharged to hospice.*

• Patients in medical cohorts with metastatic cancers.* * Medical cohorts include non-surgical cohorts: bowel obstruction, chronic obstructive pulmonary disease, diabetic emergencies, gastrointestinal bleed, heart attack, heart failure, hip fracture treatment, pancreatitis, pneumonia, pulmonary embolism, respiratory failure, sepsis, and stroke.

Cohort Definitions and Outcomes Healthgrades analyzed clinical outcomes (mortality and complications) for each of 34 condition or procedure cohorts. For each, a list of specific procedures and diagnoses that define the cohort as well as a list of exclusions representing rare and/or clinically complex diagnoses and procedures that cannot be adequately risk-adjusted were developed. A full list of ICD-9 and ICD-10 codes can be found in Healthgrades ICD-10 Mapping Tool at https://icd10mappingtool.healthgrades.com/.

Inclusion criteria for cohort analyses required at least 30 cases across three years of data and at least five cases in the most current year per hospital. As a result, the number of hospitals that qualified and received a rating ranged from a low of 450 rated for bariatric surgery to a high of 4,048 rated for pneumonia.

For 19 of the cohorts, clinical outcomes evaluated were in-hospital and 30-day post-admission mortality (see Table 1).

For 15 of the cohorts, the clinical outcome evaluated was the occurrence of one or more in-hospital complications (see Table 1). Clinical and coding experts define the complications for these 15 cohorts. A list of in-hospital complications by cohort can be found in Healthgrades ICD-10 Mapping Tool at https://icd10mappingtool.healthgrades.com/.

For the analyses, clinical outcomes were dichotomous:

• Complications were documented in the patient record as either present or not present.

• Mortality was documented in the patient record as either recorded as alive or deceased. In cohorts where the clinical outcome was complications, mortality was considered a complication.

Defining In-Hospital Complications For some procedures and treatments, Healthgrades evaluates in-hospital complications—if patients experience one or more complications during their hospital stay for a procedure or treatment.

While complications sometimes occur during a patient's hospital stay, Healthgrades pinpoints complications that should not occur with a typical patient. Many of these complications are preventable and usually cause a prolonged hospital stay, additional and costly medical treatments, harm, and sometimes even death.

In October of 2007 (fiscal year 2008), CMS began requiring most hospitals to provide a present on admission (POA) indicator for every diagnosis submitted. This indicator is intended to distinguish complications that occur during a patient’s hospital stay from those present at the time the patient was admitted to the hospital.

Hospitals excluded from the POA requirement included: critical access hospital, long-term care hospitals, cancer hospitals, children’s inpatient facilities, rural health clinics, inpatient rehabilitation or psychiatric hospitals, and federal healthcare facilities. Hospitals in Maryland generally operated under a waiver in section 1814(b)(3) of the Deficit Reduction Act of 2005 and were exempt from POA


reporting until October 2014. CMS began requiring Maryland hospitals to report POA status beginning in the 2014 fiscal year.

Table 2 shows the POA indicators listed in the 2017 MedPAR file layout document* and how they were used by Healthgrades in determining in-hospital complications in the current 2019 award year analyses. These indicators are identical to those in the all-payer state data file.

Diagnosis Records With Unknown or Empty POA Indicator When utilizing administrative patient records, Healthgrades identifies diagnosed conditions as either pre-existing or hospital-acquired. Only the hospital-acquired conditions are considered as in-hospital complications in our analyses.

To differentiate between pre-existing and hospital-acquired conditions when there is no POA indicator or the POA indicator is U (unknown), Healthgrades uses the presence of a postoperative complication code to identify a documented occurrence of a complication. For example, in the case where a patient record contains ICD-9 427.31 or ICD-10 I48.0 (Atrial Fibrillation) without a POA indicator, that code is considered a comorbid risk factor if it occurs by itself and an in-hospital complication if there is an ICD 997.1 Cardiac Complications code or one of several ICD-10 cardiac complication codes, including I97.89 (Other Post-Procedural Complications and Disorder of Circulatory System, NEC), also present in the patient record.

Healthgrades does not require the presence of a postoperative complication code for diagnoses that were clearly hospital-acquired (e.g., heart attack in an elective procedure such as total knee replacement).


Diagnosis Records With POA Indicators When there is a POA indicator present, a diagnosis is only considered an in-hospital complication if the POA indicator is set to No. This means that the condition was not present at the time of admission and was acquired during the hospitalization episode of care.

Independent vs. Dependent Complications Complications are “independent” if the condition clearly occurred during a patient’s hospital stay or if the condition is defined as postoperative by the coding definition. These conditions only require a single code to be present in order to be counted as a complication. They are not counted as a complication if the POA indicator was “Yes” or “Clinically Undetermined”. Complications described as “dependent” are conditions that must either have POA indicator set to “No” or if the POA indicator is set to “Unknown” or is missing, there must also be the listed the ICD-9 900 postoperative complication code or its ICD-10 equivalent present in the patient record. These conditions require two codes (the condition ICD code and the 900 series complication code or its ICD-10 equivalent) to be considered a complication. A full list of ICD-9 and ICD-10 codes can be found in Healthgrades ICD-10 Mapping Tool at https://icd10mappingtool.healthgrades.com/.

Multivariate Logistic Regression Models For each of the 34 cohorts, individual risk models were constructed and tailored for each condition or procedure relative to the specific clinical outcome; including, in-hospital complications, in-hospital mortality or 30-day post-admission mortality.

Healthgrades methodology uses multivariate logistic regression to adjust for patient risk factors that influence patient outcomes in significant and systematic ways. Risk factors may include age, gender, specific procedure performed, comorbid conditions. Examples of comorbid conditions that may be evaluated include hypertension, chronic renal failure, heart failure, and diabetes.

Statistically Significant Risk Factors For each cohort, comorbid diagnoses (e.g., hypertension, chronic renal failure, anemia, and diabetes), demographic characteristics (age and gender), source of patient admission, and specific procedures (e.g., percutaneous coronary intervention in heart bypass surgery) were classified as potential risk factors. Healthgrades used logistic regression to determine which of these potential risk factors were statistically significant in predicting the outcome measure (e.g., mortality). All risk factors that remained in the final model were statistically significant at the p ≤ .05 level in predicting the clinical outcome.

Risk factors with an odds ratio less than 1.0 were removed from the final model. There were occasional exceptions to this rule, determined by statistical and clinical expert review. For example, risk factors that have been documented in the medical literature to be associated with lower risk of mortality or complications and risk factors that are part of the cohort definition remained in the model even if the odds ratio was less than one (e.g., clipping of aneurysm in stroke).

Appendix B lists the coefficient summary table for each of the 19 mortality-based cohorts. Appendix C lists the coefficient summary table for each of the 15 complication-based cohorts. Included in the summary tables are the risk factor descriptions, the model coefficients, standard errors, z-statistics, and odds ratios.

The statistical models were checked for predictive ability and finalized. All of the models were predictive of the outcome being measured, with c-statistics ranging from 0.664 to 0.940. These cohort-specific and outcome-specific models were then used to estimate the probability of the outcome for each patient in the cohort (predicted probability of mortality and complications). Appendix D, Model Fit Statistics contains the c-stat with a 95% confidence interval for each risk-adjustment model by cohort.



Model Coefficient Summary and Fit Statistics Tables (See Appendix B and Appendix C for coefficient summary tables for 34 logistic regression models. For each model, tables include the following items:

• Model (factor) Coefficient – This represents the increase or decrease to the patient level log odds when the patient has the associated factor.

• Standard Error – This is a measure of variation for the coefficient.

• Z-Statistic – This is a test statistic which provides a measure of the strength of the relationship between the factor and the outcome.

• Odds Ratio – This is the most commonly interpreted component of a logistic regression model. This indicates the relative increase in the likelihood of a negative outcome (mortality or complication) when a patient has the risk factor relative to a patient who does not.

Adjustment for POA Fill Rate as an Additional Model Variable POA fill rates were included as an additional independent variable for each year of data. The POA fill rate was calculated as the percent of diagnosis codes having a known POA indicator value of Yes, No or Clinically Undetermined among patients in that cohort at that hospital.

This additional risk adjustment was necessary because critical access hospitals were exempt from POA reporting. Thus, these hospitals had lower rates of detectable in-hospital complications and conversely, more conditions potentially factored into the acuity adjustment. Testing verified that the inclusion of POA fill rates in the logistic regression model adequately adjusted for the differing overall rates of complications between hospitals reporting POA and the exempt hospitals.

Hospital Performance Once the regression models were developed, Healthgrades stratified hospital performance for each of the 34 conditions or procedures into three categories:

Better Than Expected – Actual performance was better than predicted and the difference was statistically significant at alpha = 0.1.

As Expected – Actual performance was not statistically significantly different from what was predicted at alpha = 0.1.

Worse Than Expected – Actual performance was worse than predicted and the difference was statistically significant at alpha = 0.1.

Developing the Healthgrades hospital performance categories involved four steps:

1. The hospital predicted value (predicted number of deaths or complications at each hospital) was calculated by summing the individual patient record predicted values determined from logistic regression models discussed above.

2. The hospital predicted value was compared with the actual or observed value (e.g., actual number of deaths or complications at each hospital).

3. A test was conducted to determine whether the difference between the predicted and actual values was statistically significant. This test was performed to make sure that differences were very unlikely to be caused by chance alone. A z-score was used to establish an approximate 90% confidence interval.*

4. Hospital performance star-levels were determined based upon the outcome of the test for statistical significance.


*In stratifying hospital performance categories, Healthgrades establishes a 90% confidence interval for z-score distribution with cut-offs of 1.645 standard deviations above and below the mean. The 5-star hospital performance category for a specific condition or procedure includes scores more than 1.645 standard deviations above the mean. The 1-star hospital performance category for a specific condition or procedure includes scores more than 1.645 standard deviations below the mean. Additionally, the Hosmer-Lemeshow patient level variance estimates were used to calculate hospital specific standard deviations for test of statistical significance.

Limitations of the Data Models While logistic regression models may be valuable in identifying hospitals that perform better than others for care provided during a hospital stay, one should not use this information alone to determine the quality of care provided at each hospital. The models are limited by the following factors:

• Cases may have been coded incorrectly or incompletely by the hospital.

• The models can only account for risk factors that are coded into medical claims record. If a particular risk factor was not coded into the billing data, such as a patient’s socioeconomic status and health behavior, then it was not accounted for with these models.

Please note that hospitals grouped into the 5-star category for performance in a specific cohort do not serve as a recommendation or endorsement by Healthgrades for a particular hospital; it means that the data associated with a particular hospital have met the foregoing qualifications. Individual patients should decide, in conjunction with their doctor, whether a particular hospital is suited for their unique needs.

Also note that if more than one hospital reported to CMS under a single provider ID, Healthgrades analyzed patient outcomes data for those hospitals as a single unit. Throughout this document, therefore, “hospital” refers to one hospital or a group of hospitals reporting under a single provider ID. Some hospitals that operate as a single unit submit data under multiple provider IDs. In this case, the data from the multiple provider IDs are combined and reported under the parent hospital provider ID.

Appendix E. Hospital Ratings Removal Policy Effective Date: August 16, 2015

Healthgrades evaluates the performance of the nation’s nearly 5,000 hospitals using several data sources including data submitted by hospitals to the Centers for Medicare and Medicaid Services (CMS), all-payer data submitted by hospitals to their states, and HCAHPS data.

Regardless of the data set utilized, Healthgrades methodology is applied to every hospital in the same manner.

On rare occasions, Healthgrades identifies new information that impacts its assessment of a hospital. Healthgrades policy is to remove certain hospitals’ performance and/or awards from its website in the following situations:

• A revocation of a hospital’s Medicare license by CMS;

• Federal conviction of a hospital for Medicare fraud;

• Egregious issues with the integrity of data submitted by a hospital to CMS or to the state in which the hospital resides.

In these rare circumstances, the hospital’s CEO will be notified in writing of the reason for removal. Removal is at the discretion of Healthgrades based on the impact from erroneous data and/or presumed fraudulent activities.

Under no circumstances will Healthgrades accept data directly from a hospital, nor will Healthgrades manipulate or change a hospital’s performance category or data in any way. It is the hospital’s responsibility to resubmit the data to CMS or to its state. To re-post specific performance information, Healthgrades must receive corrected data directly from CMS or from the state during its annual ratings update.
