Getting Help During Active Pain Crises in Sickle Cell Disease: Patient and Caregiver Perspectives in Canada.

What is this summary about?This is a plain language summary of an article originally published in Patient Preference and Adherence. This study aimed to identify the notable symptoms and impacts of sickle cell disease from the point of view of individuals living with sickle cell disease and their caregivers. The study also sought to understand the factors involved in individuals living with sickle cell disease' and caregivers' decisions and preferences if and when they seek care during a pain crisis. This summary describes: the symptoms experienced by adolescents and adults living with sickle cell disease and their severity; the treatments they and their caregivers prefer to use when they are experiencing a pain crisis; and the factors that go into deciding when and whether individuals living with sickle cell disease and their caregivers should seek outside help -- to go to a hospital, for example - during a pain crisis.[Box: see text][Box: see text]Link to original article here.

Development of a signs and symptoms outcome measure for caregivers of patients with methylmalonic acidemia and propionic acidemia (MMAPAQ).

BACKGROUND AND OBJECTIVE: Methylmalonic acidemia (MMA) and propionic acidemia (PA) are rare inborn errors of metabolism with shared signs and symptoms that are associated with significant morbidity and mortality. No disease-specific clinical outcomes assessment instruments for MMA and/or PA currently exist to capture the patient perspective in clinical trials. Because patients with these conditions are generally young and have cognitive impairments, an observer-reported outcome (ObsRO) instrument is crucial. We report results from qualitative research supporting development of the Methylmalonic Acidemia and Propionic Acidemia Questionnaire (MMAPAQ), a signs and symptoms ObsRO measure for caregivers of patients with MMA and/or PA. METHODS: Concept elicitation (CE) interviews were conducted with 35 participants across 2 studies who were aged ≥18 years and caregivers of patients with a confirmed diagnosis of MMA or PA, and an additional 5 patients aged ≥6 years with MMA or PA in Study 1, to identify core signs/symptoms for inclusion in the MMAPAQ. All interviews were conducted in English. Study 2 included cognitive interviews (CI) with caregivers and clinical experts to further assess content validity. CE and a conceptual framework review were also conducted with clinical experts to further support findings. RESULTS: A consistent set of signs/symptoms of MMA and PA were reported by eligible caregivers interviewed in study 1 (n = 21) and study 2 (n = 14), representing 11 patients with MMA and 20 with PA. Based on concepts reported in study 1, a draft instrument was constructed and compared with the Pediatric Quality of Life Inventory™ (PedsQL™) and Family Impact module, demonstrating face validity for measuring key signs/symptoms important to patients and caregivers. The PedsQL™ and Family Impact modules were preferred to assess patient and caregiver impacts. Two waves of CE and CIs were conducted in study 2, with wave 1 resulting in removal of 7 items and other revisions to improve clarity, and wave 2 resulting in modification of examples used for 2 items. The final instrument consisted of the following 7 items assessed over the past 7 days using a Likert-type response scale ranging from "never" to "very often": uncontrollable or involuntary movements, dehydration, rapid breathing at rest, appearing lethargic, appearing disinterested in eating, refusing to eat, and vomiting. CONCLUSIONS: This study establishes the content validity of the MMAPAQ as the first ObsRO questionnaire for measuring core signs and symptoms of MMA and PA in clinical trials and community research. Scoring and psychometric measurement properties of the MMAPAQ will be established in future studies. The PedsQL™ was found to have face validity in measuring concepts that affect the MMA and PA patient populations and should also be considered for use in clinical trials in MMA and PA.

Content validation of a daily patient-reported outcome measure for assessing symptoms in patients with Small Intestinal Bacterial Overgrowth.

PURPOSE: The aim of this study was to generate evidence supporting the development and content validity of a new PRO instrument, the Small Intestinal Bacterial Overgrowth (SIBO) Symptom Measure (SSM) daily diary. The SSM assesses symptom severity in SIBO patients, with the ultimate goal of providing a fit for purpose PRO for endpoint measurement. METHODS: Qualitative research included 35 SIBO patients in three study stages, using a hybrid concept elicitation (CE)/cognitive interview (CI) method with US patients, ≥ 18 years. Stage 1 included a literature review, clinician interviews, and initial CE interviews with SIBO patients to identify symptoms important to patients for inclusion in the SSM. Stage 2 included hybrid CE/CI to learn more about patients' SIBO experience and test the draft SSM. Finally, stage 3 used CIs to refine the instrument and test its content validity. RESULTS: In stage 1 (n = 8), 15 relevant concepts were identified, with items drafted based on the literature review/clinician interviews and elicitation work. Within stage 2 (n = 15), the SSM was refined to include 11 items; with wording revised for three items. Stage 3 (n = 12) confirmed the comprehensiveness of the SSM, as well as appropriateness of the item wording, recall period, and response scale. The resulting 11-item SSM assesses the severity of bloating, abdominal distention, abdominal discomfort, abdominal pain, flatulence, physical tiredness, nausea, diarrhea, constipation, appetite loss, and belching. CONCLUSIONS: This study provides evidence supporting the content validity of the new PRO. Comprehensive patient input ensures that the SSM is a well-defined measure of SIBO, ready for psychometric validation studies.

Patient and Caregiver Perspectives on Care-Seeking During a Vaso-Occlusive Crisis in Sickle Cell Disease: Results from Qualitative Interviews in Canada.

Purpose: There is little research on care-seeking preferences during active pain crises for sickle cell disease (SCD) patients and their caregivers. The objective of this study was to identify relevant, patient or caregiver narratives of the pain crisis experience, to understand the factors that contribute to care-seeking during a pain crisis, and to identify preferences when making care-seeking decisions during a pain crisis. Patients and Methods: Qualitative semi-structured interviews were conducted with Canadian residents with a self-reported SCD diagnosis, who were either ≥18 years of age or an adolescent between the ages of 12-18. Interviews were hosted virtually, audio-recorded, and transcribed verbatim. Results: A total of 23 individuals participated (74% female; 26% male), including six adolescents with parent dyads and 11 adults. Almost all (N = 21, 91.3%) participants were Black/African American. Participants mentioned many factors that influenced care-seeking decisions, mainly the symptom and pain experience; institutional factors (waiting time, the presence of and adherence to treatment guidelines, and the empathy or racial bias felt from medical staff); and subject-level factors (age and a flexibility in daily responsibilities). Conclusion: This study identified important institutional and subject-level considerations involved in care-seeking decisions. Most importantly, this study highlights the racial stigma faced by many patients when care-seeking in the ER and the lack of care protocol implemented, which hinders care-seeking in a dedicated medical facility. From the patient perspective, these are clear gaps to fill to encourage patients to seek and receive the care they deserve.
