This is a process measure of the annual proportion of eligible patients ≥ 18 years of age, who were prescribed aspirin, P2Y12 inhibitor, and statin at discharge following PCI with or without stenting.
Annual risk-adjusted standardized infection ratio (SIR) of observed over predicted deep incisional primary and organ/space surgical site infections (SSIs), over a 30-day post-operative surveillance period, among hospitalized adults who are >=18 year of age with a date of admission and date of discharge that are different calendar days, and the patient underwent a colon surgery (COLO) or abdominal hysterectomy (HYST) at an acute care hospital or oncology hospital. The 30-day postoperative surveillance period includes SSIs detected upon admission to the facility or a readmission to the same facility or a different facility (other than where the procedure was performed) and via post-discharge surveillance.

Impact Summary: This measure supports the PCHQR Program’s objectives by providing transparent, standardized infection ratio data that empowers consumers to make informed health care decisions and motivates hospitals and clinicians to focus on quality improvement and adherence to best practices in inpatient care for Medicare beneficiaries.
Analysis of measure performance over the past 4 years is impacted by the small number of PCHQR hospitals available to report on this measure, rather than low participation among a large eligible group.
With only seven entities per year in Figure 1a and eight in Figure 1b, distinguishing true trends from random variation is difficult, and little discernable change is observed across the 4 years. Tables 1a and 1b demonstrate potential improvements that translate to a reduction in surgical site infections of fewer than three eligible patients per entity.
For this measure, Battelle reviewed the following publicly available datasets available at Hospitals data archive | Provider Data Catalog:
Battelle analyzed all values for “PCH_6” and “PCH_7” not marked as “Not Available” from the corresponding PCH_HEALTHCARE_ASSOCIATED_INFECTIONS_HOSPITAL.csv file.
About Figure 1a and 1b: Figures 1a and 1b are boxplots that show how scores have changed based on the most recent 4 years of data available. For each year, the boxplot displays a box with lines and dots to help visualize the range and distribution of scores. The dots represent the points where the lowest 5% and highest 5% of scores fall, and the line connecting them shows where 90% of the scores are located. The box itself covers the middle half of the scores, from the 25th to the 75th percentile. Inside the box, a horizontal line marks the median score, which is the middle value, while a “+” sign shows the average score. This type of graph makes overall trends in scores over time as well as the consistency and spread of the results easier to understand.
Figure 1a. Boxplot of Measure Score by Year (Colon Surgery)
Figure 1b. Boxplot of Measure Score by Year (Abdominal Hysterectomy)
Figure 1a and 1b Interpretation: In Figure 1a, each year includes data from only seven entities, while Figure 1b includes eight entities per year. Because of this small sample size, any trends observed over the 4 years could be due to random variation rather than meaningful change. Overall, the limited number of PPS-exempt cancer hospitals participating and reporting in this program makes analyzing overall performance trends difficult. For this measure, lower scores reflect higher quality of care.
About Table 1a and 1b: Tables 1a and 1b illustrate the distribution of scores (SIRs), raw rates, and the number of patients represented within each entity. It is important to note that the entities with the lowest or highest scores may contain more or fewer patients than other entities. For example, if the lowest-scoring entity includes only 5% of the total patient population, then smaller entity size may be associated with lower performance scores.

Table 1a and Table 1b Interpretation: Note that there are data for only seven entities for Table 1a and eight entities for Table 1b. To estimate the number of negative outcomes (surgical site infections), the number of patients is multiplied by the average raw rate for each entity.
The total estimated number of negative outcomes across all entities for Table 1a is about 140. If the average performance of the lowest two entities (2.68%) is considered a plausible, achievable rate, and the other five entities improved to reach that rate, about 30 fewer colon surgery patients would experience surgical site infections. This translates to about four patients per entity and could mean that improving performance on this measure could help ensure that fewer colon surgery patients would contract surgical site infections, potentially leading to better health outcomes.
The total estimated number of negative outcomes (surgical site infections) across all entities for Table 1b is about 22. If all entities reduced the rate to 0%, 22 fewer abdominal hysterectomy patients would experience surgical site infections. This translates to less than three eligible patients per entity.

30-Day Unplanned Readmissions for Cancer Patients measure is a cancer-specific measure. It provides the rate at which adult cancer patients have an unplanned readmission within 30 days of discharge from an acute care hospital. The unplanned readmission is defined as a subsequent inpatient admission to a short-term acute care hospital, which occurs within 30 days of the discharge date of an eligible index admission and has an admission type of “emergency” or “urgent.”
Annual risk-adjusted standardized mortality ratio (SMR) of adult inpatients with community-onset sepsis who died during their hospitalization or were discharged to hospice. SMR is reported annually and is calculated by dividing the number of observed community-onset sepsis deaths by the number of predicted community-onset sepsis deaths.
Percentage of patients aged 18 years and older at the start of the measurement period with one or more inpatient encounters during the measurement period who have an advance care planning document or documentation of an advance care planning discussion resulting in a documented decision in the electronic health record (EHR) by the time of hospital discharge for at least one hospital encounter during the measurement period.
Percentage of patients aged 18 years and older admitted to a hospital with a primary diagnosis of an acute myocardial infarction or chronic stable angina or who during hospitalization have undergone coronary artery bypass (CABG) surgery, a percutaneous coronary intervention (PCI), cardiac valve surgery (CVS), or cardiac transplantation who are referred to an early outpatient cardiac rehabilitation/secondary prevention program.
Annual risk-adjusted standardized infection ratio (SIR) of catheter-associated urinary tract infections (CAUTI) among adults and children hospitalized as inpatients at acute care hospitals, oncology hospitals, long-term acute care hospitals, and acute care rehabilitation hospitals. SIR is reported annually and is calculated by dividing the number of observed CAUTIs into the number of predicted CAUTIs.
Annual risk-adjusted standardized infection ratio (SIR) of central line-associated bloodstream infections (CLABSI) among adults and children hospitalized as inpatients at acute care hospitals, critical access hospitals, oncology hospitals, and long-term acute care hospitals. SIR is reported annually and is calculated by dividing the number of observed CLABSIs by the number of predicted CLABSIs.
This is a weighted composite measure comprised of six component measures: three all-cause risk standardized outcome measures on all-cause mortality, bleeding, acute kidney injury and three process measures focused on discharge on guideline directed medical therapy, referral to a cardiac rehabilitation program and PCI performed within ninety minutes of symptoms for patients with acute myocardial infarctions. The target population includes adults (age 18 and greater) undergoing percutaneous coronary interventions. The timeframe for reporting will be a rolling four quarters.
