Development of the Bleeding and Pelvic Discomfort Scale for Use in Women With Heavy Menstrual Bleeding Associated With Uterine Fibroids.

OBJECTIVES: This study aimed to define a cardinal symptom burden measure based on items from the Uterine Fibroid Symptom and Quality of Life questionnaire for use as a clinical trial endpoint. METHODS: Exploratory factor analysis was computed to assess the Uterine Fibroid Symptom and Quality of Life symptom severity scale factor structure, using phase 2 data. Pooled blinded data from phase 3 studies were used for the confirmatory factor analysis and the psychometric evaluation of the new measure. Exit interviews in 30 patients from phase 3 studies provided additional qualitative evidence. A meaningful change threshold was determined using anchor-based analyses supported by patient feedback in the exit interviews. RESULTS: Three factors emerged from the exploratory factor analysis. Factor 1, called the bleeding and pelvic discomfort (BPD) scale, consists of cardinal symptoms, measuring menstrual distress owing to heavy bleeding, passing blood clots, and feeling tightness or pressure in pelvic area. Patients generally understood the items in the scale and the recall period as intended. The BPD scale had good item performance and internal consistency reliability, strong item-to-total correlations, good item discrimination, known-groups validity, and ability to detect change. A 20-point change on the BPD scale was determined as the clinically meaningful change threshold. CONCLUSIONS: The BPD scale assesses symptom burden owing to bleeding, passing blood clots, and pelvic pressure. The subscale is based on a subset of items selected to measure the cardinal symptoms of uterine fibroids in a clinical trial setting. The responder threshold evaluates whether patients experience a meaningful treatment benefit over the on-treatment period.

Qualitative Development of the Allergan Satisfaction with Treatment Experience Questionnaire (ASTEQ) Instrument, a Patient-Reported Outcome Measure in Glaucoma and Ocular Hypertension.

INTRODUCTION: Sustained-release intraocular implants provide a therapeutic option for open-angle glaucoma (OAG) and ocular hypertension (OHT) patients who are non-compliant with eyedrops. Currently, there are no published patient-reported outcome (PRO) measures that assess treatment satisfaction with intraocular implants. To address this gap, a new PRO instrument, the Allergan Satisfaction with Treatment Experience Questionnaire (ASTEQ), has been developed in accordance with Food and Drug Administration guidance. METHODS: Qualitative research interviews were conducted among patients with OAG/OHT who had received three intraocular injections of a sustained-release bimatoprost (10 or 15 µg) implant within the clinical trial setting. A preliminary conceptual framework capturing treatment satisfaction concepts in glaucoma, as identified from the literature, was used to develop a semi-structured interview guide. A concept elicitation (CE) interview to identify aspects of the glaucoma treatment experience pertinent to intraocular implants provided content for a draft instrument. A cognitive debriefing (CD) interview to test the instrument's interpretability, relevance, and validity informed its subsequent refinement. Interview analysis followed a grounded theory approach to identify data patterns and relationships. RESULTS: CE interviews (n = 19) indicated that participants' main considerations in rating satisfaction with implant treatment were physical comfort during preparation for the implant and implant administration, anxiety about the procedure, frequency of implant administration, possible side effects, convenience and accessibility of the implant, relationship with the clinician, and lifestyle fit. Draft ASTEQ revision based on CD interviews (n = 20) and readability tests yielded a nine-item ASTEQ instrument comprising satisfaction with overall implant experience and frequency of administration, occurrence/bother of immediate and long-term side effects, worry about implant administration and possible risks/side effects, and physical discomfort during preparation for the implant and implant administration. CONCLUSION: The ASTEQ instrument has demonstrated content validity in patients with OAG/OHT treated with a sustained-release bimatoprost implant. Further research is necessary to evaluate its psychometric properties.

Endometriosis Symptoms and Their Impacts on the Daily Lives of US Women: Results from an Interview Study.

Objective: This interview study sought to capture patients' experiences and perceptions of endometriosis symptoms and their impacts on daily life, as described by women in their own words. Using open-ended questions and a concept-elicitation approach, this study assessed the signs and symptoms of endometriosis and their impacts on different aspects of quality of life, including daily activities, functioning, and well-being. Materials and Methods: This interview study included US women with moderate-to-severe endometriosis-associated pain who completed one of two Phase 3, randomized, double-blind, placebo-controlled trials (SPIRIT 1 or SPIRIT 2; ClinicalTrials.gov identifiers: NCT03204318, NCT03204331). Interviews were conducted via a web/Internet-based video platform or telephone by trained interviewers, using open-ended questions in a concept-elicitation approach, and probes as needed to obtain additional feedback on the burden of endometriosis. Qualitative data from the interviews were analyzed, and emerging concepts were coded by independent coders. Concept saturation was evaluated to determine if all endometriosis-related symptoms and impacts had been described by the sample of women interviewed. Results: Forty women participated in this study. In total, 18 unique symptoms of endometriosis emerged from the interviews; pelvic pain (92.5%), dyspareunia (80.0%), and heavy bleeding (75.0%) were the most commonly reported endometriosis symptoms. A total of 33 unique impacts of endometriosis symptoms were identified across 11 concepts: physical impacts, impacts on activities of daily living, social impacts, sleep impacts, emotional impacts, appearance impacts, financial impacts, sex-related impacts, work/school-related impacts, fertility impacts, and cognitive impacts. Concept saturation was achieved for both symptoms and impacts of endometriosis. Conclusion: This interview study provides substantive qualitative data on the burden of endometriosis, from the perspective of affected women in the US. The findings demonstrate the debilitating effect of endometriosis symptoms, which limit and adversely impact women's daily lives.

Development of a Novel Tool to Assess the Impact of Itching in Pediatric Cholestasis.

OBJECTIVES: The aim was to develop a clinical outcome assessment (COA) for itching in children with cholestatic pruritus. METHODS: This prospective study aimed to enroll patients aged 4-30 years with Alagille syndrome (ALGS) or progressive familial intrahepatic cholestasis type 1 and caregivers of patients aged 5 months to 14 years. Eligible patients experienced itching during ≥3 of the 7 days before enrollment and had not undergone liver transplant or surgical interruption of the enterohepatic circulation. Open-ended qualitative interviews confirmed that itching was a primary concern for patients and caregivers. Diaries were modified and then evaluated by participants during cognitive debriefing. Interview results were reviewed by clinical, COA and statistical experts. Diary questions were revised following an interim analysis before finalizing the Itch Reported Outcome (ItchRO). RESULTS: Thirty-six interviews were analyzed, representing 25 families of patients with ALGS. Itching was reported spontaneously (without prompting by the interviewer) by ten of 12 patients with ALGS and 19 of 20 caregivers. Consequences of itching included skin damage (78%), mood changes (59%), and difficulties staying asleep (59%) or falling asleep (53%). Two versions of the ItchRO were developed: ItchRO(Patient) for self-completion by patients and ItchRO(Observer) for caregivers. The ItchRO diaries comprise a single scorable item to assess itch and are to be completed twice daily (morning and evening). CONCLUSIONS: Itching was the most bothersome ALGS symptom reported by study participants. We have developed the ItchRO(Patient) and ItchRO(Observer) to assess itching in children with ALGS and other cholestatic liver diseases. These diaries are being validated for use in clinical trials.
