Negative Pressure Wound Therapy - Essay Example

"Negative Pressure Wound Therapy" is a perfect example of a paper on Injuries and Wounds. A PICOT question helps in outlining the primary components of evidence-based research. For this study, the question will focus on pressure ulcers/wound care among the patients in geriatric care. The question states: For patients in a geriatric population, does negative pressure wound therapy together with dressing in comparison with dressing alone, hasten the wound healing process within ten weeks? According to the PICOT question, the study population includes patients in the geriatric wards.

The intervention is negative pressure wound therapy together with the dressing. The response is compared to the use of dressing alone as an intervention. The expected outcome is an improved rate of wound healing among the patients selected for one month.Evidence-Based StudiesRelation to the PICOT QuestionThe study will involve both qualitative and quantitative research materials to help in the validation of the presented PICOT question. A pressure ulcer occurs due to the compression of soft tissue over a given surface, leading to localized tissue hypoperfusion.

According to Matiasek et al. (2018), a qualitative study, healing improves drastically when negative pressure healing is applied in collaboration with dressing. The article will help to affirm the significance of negative wound pressure therapy in the management of pressure ulcers among geriatric patients. Another qualitative study by Khansa et al. (2019) reviews fifty-nine studies investigating silver lining therapy as a negative pressure wound care intervention. The third qualitative study by Costa et al. (2018) examines the response of negative wound pressure therapy in a surgical unit involving patients with lower limb fractures.

A quantitative study by Dehghani et al. (2017) also affirms that healing time is significantly increased for the group with negative pressure methods over the conservative dressing methods alone. Another quantitative study by Gargano et al. (2017) suggests that negative pressure methods have a high-level efficacy in improving the healing process and with low recurrence rates. The third quantitative study by Strugala & Martin (2017), is a retrospective, quantitative meta-analysis of 1863 patients subjected to negative wound pressure therapy as a prophylactic measure.

For geriatric patients, it is expected to reduce to about 30 days. Wound healing via the negative pressure method, in collaboration with dressing, is more effective than conservative dressing alone. Qualitative/Quantitative, Purpose Statement and Research QuestionAll the first three studies discussed above are qualitative. This is because data analysis is done through qualitative means. The responses are indicated qualitatively. The purpose statement of the studies focuses on negative wound pressure therapy.

Different methods are used, such as the silver lining therapy in the study by Khansa and others. Their research questions focus on wound care through negative pressure means. This helps to affirm the significance of the method over the use of dressing alone as required by the PICOT question. The last three studies discussed above are quantitative. This is identified by the fact that data is analyzed quantitatively and presented through quantifiable statistics. Their purpose statements and research questions also revolve around negative pressure wound therapy as a method of managing pressure ulcers.

They help in addressing the PICOT question, which compares that to dressing alone.Setting, Sample, Methodology, and Results (Outcome)The study by Dehghani et al. (2017) is conducted in a clinical area through a prospective randomized clinical trial methodology. A sample of 24 patients was used. The outcome indicates that healing time reduces with the use of negative wound pressure therapy. Gargano et al.'s (2017) study is also conducted in a clinical area using a sample of two groups with 11 and 9 patients.

The study adopts a quantitative prospective study whose outcome indicates that a low recurrence rate of 12% is associated with negative wound pressure therapy compared to 60% in the control group. The survey by Strugala & Martin (2017) is a retrospective study involving different articles. The sample of 1863 articles representing patients indicates an increase in hospital discharge when using negative pressure wound therapy. The qualitative study by Matiasek et al. (2018) uses 13 patients and a prospective study methodology in a clinical setting.

The outcome indicates that healing time is 30 days when negative wound pressure therapy is applied and 90 days in other methods. The study by Costa et al. (2018) investigates patients in acute care with limb fractures. It also adopts a retrospective methodology. The results document different intervention measures using both the negative wound pressure therapy and other methods. Khansa et al. (2019) also adopt a qualitative retrospective methodology approach to validate the significance of silver as a method of negative pressure wound care.

The outcome for a sample of 59 studies indicates low-quality research on silver intervention and a positive effect of negative pressure wound therapy on wound care.
