The minimum data set (MDS) is a federally mandated assessment of all residents in Medicare or Medicare certified long-term health care facilities.

It provides a comprehensive assessment of each residents functional capabilities and helps members of the interdisciplinary team identify health problems and develop individualized care plans.

MDS 3.0 is the latest version of the assessment that has been designed to be more reliable, accurate and useful (1).

Section K is one of the 21 sections of the MDS that covers swallowing disorders, height and weight, weight loss and nutritional approaches (2).

This article serves as a beginners guide for dietitians on the components of the MDS 3.0 Section K.

Section K: Swallowing and Nutritional Status

The items in section K are intended to assess conditions that could affect the resident’s ability to maintain adequate nutrition and hydration.

Poor nutritional and hydration status can prolong wound healing and increase risk of pressure ulcers.

Section K covers:

K0100: Swallowing Disorder

K0100 swallowing disorder

Alterations in the ability to swallow safely can cause choking and aspiration, which can increase the resident’s risk of malnutritiondehydration and aspiration pneumonia.

The purpose of K0100 is to assess for signs and symptoms of swallowing difficulties during the 7-day look-back period.

To assess swallowing:

  • Ask the resident about each of the symptoms in A through D.
  • Observe the resident during meal and snack times.
  • Interview all staff on all shifts that work with the resident.
  • Review all notes and medical records.

K0200: Height and Weight

K0200 height and weight

Height and weight measurements assist staff with assessing the resident’s nutrition and hydration status over time.

To assess height:

  • Base on most current height.
  • Measure and record height to the nearest whole inch.
  • Measure height consistently over time with the facility policy and procedure.
  • Height should always be obtained on admit, every readmit and annually.

To assess weight:

  • Base on most recent weight in the last 30 days. Weight cannot be after the assessment reference date (ARD).
  • Round weight to the nearest whole pound.
  • Measure weight consistently over time and in accordance with facility policy and procedure.
  • If last weight was recorded more than one month ago measure and record new weight.

K0300: Weight Loss

K0300 weight loss

Weight loss can negatively affect health, safety and quality of life. For those who are obese or have fluid overload, however, weight loss may improve health status.

To assess weight loss:

  • For new admissions, ask the resident or family about weight loss over the past 30-180 days
  • For subsequent assessments, compare the resident’s weight in the current observation period to their weight in the observation period 30 days ago.
  • Calculate weight loss percentage using rounded weights.

K0310: Weight Gain

K0310 weight gain

Weight gain can negatively affect many aspects of life and therefore should be monitored on a continuing basis.

To asses weight gain:

  • For new admissions, ask the resident or family about weight gain over the past 30-180 days.
  • For subsequent assessments, compare the resident’s weight in the current observation period to their weight in the observation period 30 days ago.
  • Calculate weight gain percentage using rounded weights.

K0510: Nutritional Approaches

K0510 nutritional approaches

Nutritional approaches that include any mechanically altered diet or that rely on entereal or parenteral nutrition can diminish a resident’s quality of life. That said, alternative nutritional approaches should be monitored to validate effectiveness.

To assess nutrition approaches:

  • Review the resident’s medical record to determine if any of the nutritional approaches A through D were preformed during the 7-day look-back period.

K0710: Percent Intake by Artificial Route

K0710 percent intake by artificial route

Complete this only if Column 1 or Column 2 or both are checked for K0510A or K0510B or both.

To assess percent intake by artificial route:

  • Review intake records and determine intakes through parenteral or tube feeding routes.
  • Calculate proportion of total calories received from those routes.

The Bottom Line

MDS 3.0 Section K focuses on assessing residents’ swallowing and nutritional status.

The components in section K are intended to assess conditions that could affect a resident’s ability to maintain adequate nutrition and hydration.

It covers swallowing disorders, height and weight, weight loss and nutritional approaches.
