Description of Study Protocol:

Recruitment

None described.

Design

Guided observation of mealtime activities (meal delivery, nurses' help with position change and bed table adjustment, time of access to the meal and reason for delayed access, patients' eating difficulty and nurses' assistance, interruptions and social interaction, checking food intake and documentation) 12 times during a week (four times for breakfast, four times for lunch and four times for dinner). 

Statistical Analysis

Data were analyzed using descriptive statistics and thematic analysis.

Data Collection Summary:

Timing of Measurements

Each ward was observed 12 times during a week (four times for breakfast, four times for lunch, and four times for dinner).

Dependent Variables

  • Checking food intake
  • Documentation.

Independent Variables

  • One ward had changed staff meal break times so that nurses did not have their breaks when patients were eating their meals
  • One ward allowed staff meal breaks while patients were eating their meals.

Other Findings

  • Older patients did not receive enough assistance during mealtimes
  • Interruptions happened frequently and social interaction was neglected
  • About one-third of patients observed left more than two-thirds of their meals. 
Author Conclusion:

Nutrition issues appeared to receive less priority in the ward than other nursing care activities and nurses' assistance was generally insufficient and not provided in a timely manner. In order to improve nurses' practice at meal times, simply increasing staff numbers may not be enough; we may need to consider education to change or refocus nurses' attitudes and perceptions about the importance of nutrition. Meal delivery should be undertaken or supervised by nursing staff. During mealtimes, nurses need to spend more time assisting patients with eating rather than attending to other tasks. Providing enough assistance with opening, describing the meal and giving encouragement to eat are important, and help should be given in a timely manner. Interruption should be avoided during eating and social interaction should be emphasized.

Reviewer Comments:
  • The authors did not address the original objective, which was to describe differences in feeding practices between one ward where nurses took breaks during patient mealtimes and one ward where they did not take breaks during patient mealtimes
  • Authors note limitations of the small sample size for observation and limited ability to generalize findings.

 

Quality Criteria Checklist: Primary Research
Relevance Questions
  1. Would implementing the studied intervention or procedure (if found successful) result in improved outcomes for the patients/clients/population group? (Not Applicable for some epidemiological studies) Yes
