Literature Review

Pulmonary hypertension (PH) is a slowly and gradually deteriorating life-threatening health issue that is not frequently identified in time due to the vagueness of its initial symptoms. The problem contributes to the further deterioration of the health issue and poor health outcomes of PH patients. The practice environment to be used in the project is an outpatient cardiopulmonary care clinic in the Southern part of the United States. Lots of patients visit the clinic presenting with unclear shortness of breath and other cardiopulmonary symptoms (Executive Nurse, personal communication, February 15, 2026).

An apparent practice gap is present in the setting since the health conditions providers are not very aware of the early signs of PH. Referrals are also not a normal practice in the clinic. The disparity creates a delay in diagnosing and accessing PH specialists in a timely manner. The project population, intervention, comparison, outcome, and timeframe (PICOT) question is the following: In nurses whose patients have pulmonary hypertension in an outpatient cardiopulmonary clinic (P), how the implementation of a structured education and referral support program (I) versus the existing standard practice (C) can change the time to specialty referral (O) after 12 weeks?

The search of recent scholarly publications conducted was performed on databases, including PubMed, the cumulative index of nursing and allied health literature (CINAHL), and PsycINFO, among others, and within the period 20222026. It has set three themes: delays in diagnosis, delays in referral, and the role of nurse-led interventions. The review highlights that it is important that recognition be led by nurses to minimize delays in diagnosis, particularly among patients with pulmonary hypertension.

Thematic Synthesis of Literature

Theme 1: Delayed Diagnosis and Its Clinical and Economic Consequences 

The late diagnosis of pulmonary hypertension is an important clinical issue that has quantifiable implications. The problem is always illustrated in the literature. The survey done by Pisana (2024) suggests that the average duration between the time a patient first visits a doctor and is diagnosed with PH is approximately 17 months. There is a possibility that during the time, patients can see a number of healthcare professionals, indicating that the condition is highly inefficient in diagnosing it in time. There is also more evidence of the problem in the cohort studies. As an example, Kubota et al. (2023) demonstrated that poor clinical outcomes are linked to the delayed diagnosis of PH.

These are low rates of survival and worsened right heart functioning. The problem is also better informed in economic studies. It was demonstrated in (DuBrock et al., 2023) that the late diagnosis of PH is related to the high costs of healthcare. All these studies have revealed that when diagnosis is delayed, disease advances, death rates go higher, and expenses go up.

Theme 2: Barriers to Early Recognition and Specialist Referral

The study has shown that a certain number of barriers lead to a delay in referring patients with pulmonary hypertension to PH specialists. The issues are connected to both the practice of the providers and the healthcare system organization. As an illustration, a population survey conducted by Gillmeyer et al. (2025) shows that a very small percentage of patients are referred to PH specialist care, as should be the case. The disparities experienced in the research are attributed to the location of the patients, their socioeconomic status, and other health complications. Gillmeyer et al. (2025) used a qualitative study to gain an idea about other barriers, e.g., a knowledge gap among providers, absence of an effective care coordination process, and non-standardized referral processes.

Small et al. (2024) based on the interpretation of the barriers revealed that before a diagnosis is made, patients undergo several providers due to the ease with which nonspecific symptoms can be misinterpreted. The studies show a causal connection between the absence of knowledge among the providers and the absence of adequate coordination of care, as well as non-standardized referral processes. Therefore, patients take a longer time not only to be referred to a specialist but also to be properly diagnosed. This has not only been blamed on the complexity of the disease, but also on the failure of the healthcare system.

Theme 3: Structured and Nurse-Supported Interventions as Solutions

Compared to the identified challenges, the general literature gives coherent views that structured approaches using nurse support can be effective in the case of early detection and referral with pulmonary hypertension. According to the research by Tsai et al. (2024), timely diagnosis and prompt treatment referral may have a great influence on survival and slow down the course of the disease. Simulation studies also support the findings by showing that early intervention could reduce length of stay in the hospital and overall long-term outcomes (Alsumali et al., 2025).

There is also one more argument supporting the role of nurse-led care based on the research of Chen et al. (2023), stating that the multidisciplinary PH care programs that extend the role of the nurse in the process of coordination can have an effect on increasing the continuity of care, along with accelerating the referral to specialist care services. Meanwhile, it has been shown that team-based care models, which entail the input of multiple disciplines, are able to enhance the clinical management of patients with pulmonary hypertension significantly because they lead to the implementation of coordinated decision-making in the management of the condition. Guo et al (2025) also report that nurse-led care with care guidelines can positively affect the survival rates and reduce re-hospitalization rates compared to conventional care.

Though other studies concentrated on the system-wide care approach to the patients, and others concentrated on direct nurse-led care, the overall theme is evident. Better coordination, education, and standardization result in better early detection and referral of PH patients. This results in better outcomes for pulmonary hypertension patients compared to the traditional methods of care. On the whole, it can be concluded that the evidence-based solutions that can enhance the current provider and system-level issues in the care of individuals with pulmonary hypertension are nurse-led care and structured approaches.

Conclusion

According to the literature, the challenges that affect the victims of pulmonary hypertension include delayed diagnosis and referral. The problem affects the treatment of the patients and the efficient utilization of health resources in a twofold manner. A majority of the literature, however, has been pointing to a lack of provider knowledge, the absence of a referral system, and fragmented treatment as the cause of such a late diagnosis and referral. Conversely, it has been demonstrated that a multidisciplinary approach that includes a nurse is both practical in the early detection of health issues and in accelerating referral to special care.
