AHRQ's Safety Program for Nursing Homes: On-Time Pressure Ulcer Prevention
Functional Specifications
3. Specifications for Each Pressure Ulcer Prevention Report (continued)
3.3. Weight Summary Report
3.3.1. Report Description
The Weight Summary Report displays 4 weeks of trended weight information for each resident, calculates weight changes, and displays whether there have been measurable weight loss percentages (more than 2 percent, 5 percent, 7.5 percent, and 10 percent) for the past 7, 30, 90, and 180 days).
3.3.2. Dependencies and Clinical Assumptions
3.3.2.1. Resident weights are stored in the EMR.
3.3.2.2. Active residents only display for a single nursing unit.
3.3.3. Report Example
Resident Name | Resident ID | Weight 180 Days Prior | Weight 90 Days Prior | Weight 30 Days Prior | Weight for Week 5/8/14 Week4 | Weight for Week 5/15/14 Week3 | Weight for Week 5/22/14 Week2 | Weight for Week 5/29/14 Week1 | Weight Change lbs / Date | ≥2% Wt. Loss (From Previous Week) | ≥5 lb Wt Loss in Prior 30 Days | ≥5% Wt Loss in Prior 30 Days (Point-to- Point) | ≥5% Wt Loss in Prior 30 Days (Any) | ≥7.5% Wt Loss in Prior 90 Days | ≥10% Wt Loss in Prior 180 Days |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

3.3.4. Valid Input, Calculations, and Displays
3.3.4.1. Weights are calculated in two ways:
- Point-to-Point: using two data points to determine if weight loss occurred.
- Any Weight Loss: using multiple weight comparisons within a specified period to identify "Any" weight loss within the period.
3.3.4.2. Display weight to one decimal point, e.g., 101.5.
3.3.4.3. A date next to a weight loss value indicates the date the weight change occurred.
3.3.4.4. If a weekly weight value is not stored, then a weekly weight cell will be BLANK.
3.3.4.5. If a resident was not weighed during the current week:
- Weight values that display for 180 days prior, 90 days prior, and 30 days prior are computed using the most recent weight value that is stored in the system.
- The following cells must be BLANK:
- Weight for current week.
- Weight change in pounds/date.
- ≥2% Wt Loss (From Previous Week).
- ≥5 lb Wt Loss in Prior 30 Days.
- ≥5% Wt Loss in Prior 30 Days (Point-to-Point).
- ≥5% Wt Loss in Prior 30 Days (Any).
- ≥7.5% Weight Loss in Prior 90 Days.
- ≥10% Weight Loss in Prior 180 Days.
3.3.4.6. Display in the report footer:
All weight loss calculations are point-to-point unless "Any" is indicated.
Weight 30 Days Prior value may not be the same as Weight for Week 4 because the 30 Days Prior value date may fall outside of Week 4.
Report Column | Data Source | Valid Input & Display |
---|---|---|
Weight 180 Days Prior | Vital Signs or Weight documentation | The weight of the resident approximately 180 days prior to the most recent resident weight. Static Week Calculation:
|
Weight 90 Days Prior | Vital Signs or Weight documentation | The weight of the resident approximately 90 days prior to the most recent resident weight. Static Week Calculation:
|
Weight 30 Days Prior | Vital Signs or Weight documentation | The weight of the resident approximately 30 days prior to the most recent resident weight. Static Week Calculation:
|
Weight for Week | Vital Signs or Weight documentation | Lowest weight for each week in a 4-week period trended view. Week Ending Date should be displayed in the four column headers.
|
Weight Change (lbs) | Vital Signs or Weight documentation | Change in weight (lbs) from the previous weight to the most recent weight (Most Recent Weight − Previous Weight).
|
≥2% Weight Loss (From Previous Week) | Vital Signs or Weight documentation | Displays the weight loss value of a resident with weight loss ≥2% from the previous week to the most recent week (where the 2 weeks are adjacent to one another). Static Week Calculation: Take the weight change in lbs from the previous week to the most recent week (most recent − previous) If weight change is positive, disregard; if negative, take absolute value, and divide by the previous week’s weight. Multiply by 100. Indicate with % sign. Show rounded to one decimal place. Display value if ≥2%. |
≥5 lb Weight Loss in Prior 30 Days | Vital Signs or Weight documentation | Displays the value of a resident weight loss of ≥5 lbs approximately 30 days prior to the most recent weight. Static Week Calculation:
|
≥5% Wt Loss in Prior 30 Days (Point-to-Point) | Vital Signs or Weight documentation | Note: The calculations below will identify weight loss closest to 30 days from most recent weight. Displays the occurrence of a resident weight loss of ≥5% compared to weight closest to 30 days prior. Static Week Calculation:
|
≥5% Wt Loss in Prior 30 Days (ANY) | Vital Signs or Weight documentation | Note: The calculations below will identify ANY weight loss within the last 30 days. Displays all occurrences of a resident weight loss of ≥5% in the last 30 days. Static Week Calculation:
|
≥7.5% Wt Loss in Prior 90 Days | Vital Signs or Weight documentation | Displays weight loss ≥7.5% in 90 days. Static Week Calculation:
|
≥10% Wt Loss in Prior180 Days | Vital Signs or Weight documentation | Displays resident weight loss ≥10% in the last 180 days. Static Week Calculation:
|
* | Physician Orders | Indicates resident has active dialysis order. |
