“…The ND ineffective peripheral tissue perfusion (00204) was the only diagnosis identified by all experts. This result is explained by the fact that the patient having PAOD is characterized by a series of structural dysfunctions that result in reduced peripheral arterial blood flow, compatible with the definition of the ND ineffective peripheral tissue perfusion and with the clinical manifestations these patients have (da Silva Júnior et al., 2015; Herdman et al., 2021). It was already expected that the ND ineffective peripheral tissue perfusion would be considered highly accurate since the case was developed with several cues found in the literature.…”

PurposeThe aim of this study is to develop and validate a case study to aid in the diagnostic reasoning of nursing students and nurses.MethodsIt is a validation study using a case study based on Lunney's method including (1) content validation of the case study by nurse experts through the Delphi technique, (2) identification of nursing diagnoses (NDs) in the case, (3) evaluation of diagnostic accuracy, and (4) establishment of a priority diagnosis by nurse experts.FindingsThe case study was developed from the findings of a narrative literature review on the cues of the NDs with a prevalence > 50% in patients with peripheral arterial occlusive disease. Two rounds of expert evaluation were required to validate the case study. The experts identified 18 NDs with different degrees of accuracy. The highly accurate diagnoses most frequently identified by the experts were: Ineffective peripheral tissue perfusion (100%), impaired walking (83%), impaired comfort (50%), and chronic pain (50%). The diagnosis considered a priority by all experts was ineffective peripheral tissue perfusion.ConclusionsThe case study was developed and had its content validated. High‐accuracy diagnoses were identified, and a priority was determined.Implications for Nursing PracticeThe validated case study may be used by students and nurses to facilitate the development of diagnostic reasoning and critical thinking in practice, teaching or research.

“…This is frequently atherosclerotic in origin, and is considered a coronary artery disease equivalent. [1][2][3] In the Philippine setting, the prevalence of PAD among the general adult population increased from 0.4% in 2003 to 1.2% in 2008. 4 In patients with diabetes, the prevalence of PAD increases with age, from 20% in those over 40 years of age to 29% in those over 50 years.…”

Objective. The main objective is to determine if digital pulse oximetry is an acceptable screening tool to detect hemodynamically significant lower extremity peripheral artery disease (PAD) in patients 50 years old and above with type 2 diabetes mellitus (T2DM) seen at the University of Santo Tomas Hospital (USTH).Methodology. A total of 78 subjects (155 limbs) were included. Using duplex ultrasonography as the reference standard for the presence of hemodynamically significant lower extremity PAD, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were obtained for abnormal percent oxygen saturation (SpO 2 ) gradients and for ankle-brachial index (ABI).Results. Of the 155 limbs, 38.7% had hemodynamically significant stenosis. Pulse oximetry had 76.7% sensitivity (95% CI, 65.2% to 88.1%), 85.3% specificity (95% CI, 78.0% to 92.6%), 76.7% PPV (95% CI, 66.5% to 84.4%) and 85.3% NPV (95% CI, 78.4% to 90.2%). ABI had 40.7% sensitivity (95% CI, 30.1% to 51.3%), 88.2% specificity (95% CI, 80.0% to 96.3%), 68.6% PPV (95% CI, 53.6% to 80.4%) and 70.1% NPV (95% CI, 65.1% to 74.5%). Combining both produces 88.1% sensitivity (95% CI, 78.5% to 97.8%), 74.2% specificity (95% CI, 65-83.4%), 68.4 PPV (95% CI, 60.3% to 75.6%) and 90.8% NPV (95% CI, 83.0% to 95.2%). Conclusion.The results of this study suggest that pulse oximetry has a higher sensitivity than ABI as a screening tool for hemodynamically significant lower extremity PAD in T2DM patients 50 years old and above. Combining these two tests may be done to achieve a higher sensitivity.

Background Provoked gluteal claudication is a known risk after endovascular aortic repair (EVAR). Lowered gluteal muscle oxygenation (S gm O 2 ) may be demonstrated by near-infrared spectroscopy (NIRS). Purpose To evaluate NIRS-determined S gm O 2 in EVAR patients. Material and Methods NIRS-determined S gm O 2 was used in an observational study design (n = 17). From the ambulatory setting, seven EVAR patients were included with reported gluteal claudication from medical records. In 10 patients scheduled for EVAR, S gm O 2 was measured before and after the procedure. NIRS sensors were applied bilaterally on the gluteal region. Treadmill walking (12% incline, 2.4 km/h) was introduced to stress gluteal muscles. Results A reduced S gm O 2 with regional side difference ( P < 0.05) was noted in all 10 patients following EVAR and four reported gluteal claudication. In patients with gluteal claudication (n = 7), treadmill decreased S gm O 2 . The time to recover the S gm O 2 was prolonged for tissue exposed to occluded hypogastric artery (median = 512 s, range = 73–1207 s vs. median = 137, range = 0–643 s; P = 0.046). Conclusions EVAR affects gluteal muscle oxygenation. NIRS could be used to assess whether gluteal claudication is related to lowered S gm O 2 .
