Background
Patient experience is a well-recognized, independent dimension of health care delivery. Although considerable progress has been made in the diagnosis and management of venous thromboembolism (VTE), data on the patient experience are lacking. We aimed to capture patients' experiences with VTE and anticoagulation in order to prioritize efforts to improve VTE health care delivery.
Methods
An IRB-approved survey was developed with a multidisciplinary team of clinicians and patient advocates. The survey domains included patient demographics, health care experiences, perspectives, and potential gaps in healthcare received for VTE. The survey was pilot tested and subsequently distributed electronically from May-July 2023 through an international patient advocacy group targeting individuals with personal history of VTE. Data are described as counts and proportions. We used log binomial regression to calculate the risk ratios (RR) and 95% confidence intervals (CI) of outcomes associated with seeing a hematologist during or after hospital admission.
Results
Of a total of 1,050 participants, the majority were from the US (81%), including 49 states and the District of Columbia. A response rate could not be calculated given that the web-based survey was openly distributed. The majority of respondents were women (81%), 88% identified as white, and 71% were age 40-69 years. Most patients (68%) experienced their first VTE event &gt;12 months prior to the study, 36% had &gt;1 VTE events and the majority (62%) were diagnosed in the emergency department.
Over one-third (35%) of respondents reported not receiving the correct diagnosis the first time they presented to medical care and 50% of these participants had at least 3 health care visits before reaching the correct diagnosis. The majority (93%) recall information regarding their VTE diagnosis was provided by physicians or advanced practitioners, 65% reported this conversation was &lt;10 minutes, and only 55% felt the diagnosis was explained to their satisfaction. (Table) A minority (16%) of patients received printed or electronic information at the time of diagnosis. Almost all (97%) participants were treated with anticoagulation, but only 48% recalled being provided specific information about the medication including risks and benefits. Only 24% of 563 respondents who menstruate recall discussing the impact of anticoagulation on menstruation with providers, and all recalled discussing this only after they developed anemia or changes in their menstrual flow. Of the 105 participants who were offered the opportunity to speak with a health care advocate, most (73%) accepted it; of those not offered an advocate, 88% reported that they would have accepted the opportunity. Only 53% of respondents reported access to providers for questions regarding their VTE diagnosis.
Of 702 patients who were admitted to the hospital for VTE, 32% reported returning to health care, as their symptoms did not improve or worsened, and 30% of these patients were readmitted. Most admitted patients (89%) reported receiving some information about VTE at discharge, but the information received did not match the topics patients wanted. For example, patients most frequently wanted information about support groups (65%), mental health (65%), recurrence risk (55%) and prevention strategies (49%), but few received this information (2%, 2%, 17%, and 33%, respectively (Figure).
Most patients were seen by hematologists following discharge (59%) or during hospitalization (35%). Among admitted patients, those who saw a hematologist either during or after admission were significantly more likely to receive information about their VTE (RR: 1.15, 95% CI: 1.06-1.24) and about anticoagulation (RR: 1.23, 95% CI: 1.04-1.45) at discharge compared to patients who did not see a hematologist.
Conclusion
In this first large-scale international survey to capture patient experiences and gaps in VTE care delivery, we identified several potential areas for improvement. Efforts to enhance patient education could improve the patient experience. Further research could explore if better education translates to improved medication adherence, management of bleeding, avoiding polypharmacy, and ultimately clinical outcomes. Professional societies and patient advocacy groups can partner to build resources to improve the quality of care and patient satisfaction for people with VTE.
