PEG Tubes vs. NGT Feeding: Quality of Life in Stroke Patients
This paper proposes a comparative study examining how two common enteral feeding methods — percutaneous endoscopic gastrostomy (PEG) tubes and nasogastric tubes (NGT) — affect the quality of life of dysphagic stroke patients. While existing research has focused primarily on clinical outcomes such as malnutrition prevention and survival rates, this study shifts attention to patient-reported satisfaction, particularly regarding the ability to undergo therapy to regain speech and swallowing function. Using a structured yes/no survey administered to 25 PEG patients and 25 NGT patients in long-term care settings, the study hypothesizes that PEG feeding will yield significantly higher quality-of-life satisfaction scores, as measured by descriptive statistics and z-test analysis.

What makes this paper effective
- Clearly identifies a gap in existing research — the lack of patient-centered, quality-of-life measures in PEG vs. NGT studies — and builds the rationale for the proposed study around that gap.
- Grounds the research question in a practical clinical context, making the study design feel purposeful and relevant to healthcare practitioners.
- Proposes an accessible, patient-sensitive methodology (yes/no verbal survey) that accounts for the physical and communicative limitations of the target population.
Key academic technique demonstrated
The paper demonstrates effective use of a research proposal structure: it reviews existing literature to establish what is not yet known, formulates two specific research questions, then walks through sample selection, measurement tools, study design, and statistical analysis methods in logical sequence. This progression from problem identification to methodology is the defining feature of a well-structured research proposal.
Structure breakdown
The paper opens with a literature-grounded introduction that defines the clinical problem and justifies the research focus. A background section contextualizes PEG and NGT feeding methods and reviews prior studies. The Methods section is subdivided into Sample, Measures, Design, and Data Analysis — each addressing a distinct methodological concern. The Conclusion acknowledges confounding variables, proposes extensions (longitudinal design), and closes with a patient-centered argument for why quality-of-life research matters alongside clinical outcomes.
Introduction
Stroke can affect neurological functioning and impair a patient's ability to talk and swallow. This condition can lead to severe malnutrition, and a decision is often made to feed the patient using a tube feeding method. Many studies have been performed to measure the clinical outcomes of these procedures, but few have focused on the effects on the patient's quality of life after receiving these interventions. This study will measure the effects of having a percutaneous endoscopic gastrostomy (PEG) tube inserted on the patient's quality of life as it relates to their ability to communicate and swallow.
Two research questions will be addressed: "Does a PEG procedure have an effect on the patient's ability to communicate their wishes and improve their satisfaction with the quality of their life in regards to self-care?" and "Does the PEG method offer more satisfaction in regards to quality of life than the NGT method?"
