The reliability and validity of the impact on lifestyle questionnaire in patients with acromegaly

Do We Need a Specific Guideline for Assessment and Improvement of Acromegaly Patients Adherence?

Background: Adherence to therapy is one of the most important elements during the therapeutic process ensuring the predefined therapeutic outcomes. The aim is to analyze the need and importance of treatment adherence guideline for acromegaly patients and the possibilities for its development and implementation in Bulgaria. Methods: A set of methods was applied: (1) a literature review in the electronic database for identification of articles and guidelines related to adherence and acromegaly; (2) analysis of Bulgarian legislative documents; (3) a pilot study for assessment of the level of treatment adherence among hospitalized Bulgarian acromegaly patients in 2018; (4) a plan for development and implementation of specific guideline was created entitled BULMEDACRO - BULgarian guideline for MEdication aDherence assessment and improvement in ACROmegaly. Results: No specific guidelines for evaluation, monitoring, reporting and/or improving adherence in acromegaly patients has been found in the literature. Requirements for regular assessment of the level of adherence, application of appropriate methods for improvement and monitoring are not sufficiently formulated and mandatory. The pilot study confirmed that therapy adherence among Bulgarian patients with acromegaly is relatively high as almost 90% of patients report that they strictly comply with their prescribed treatment regimen. It is necessary, however, a specific guideline focused on the methods for assessment and improvement of adherence, in order to ensure monitoring and follow-up of acromegaly patients. Conclusions: Patients with acromegaly should be the focus of specially designed national programs, initiatives and/or guidelines for regular evaluation and improvement of the adherence level. Despite the difficulties and the lack of an adequate legal basis, successive steps initiated by different stakeholder are needed.

Evaluation of Nurses' and Patients' Overall Satisfaction with New and Previous Formulations of Octreotide Long-acting Release (Sandostatin LAR®): A French Observational Study

INTRODUCTION

The first long-acting release (LAR) formulation of octreotide was marketed in France in the late 1990s. An injectable formulation of Sandostatin LAR^® (Novartis SAS) with a new diluent has been developed to facilitate its preparation and administration and to improve its use in practice.

METHODS

We conducted an observational, cross-sectional and multicenter study in France whose main outcome was to compare nurses' satisfaction with the preparation and administration of both previous and new formulations of octreotide LAR. Secondary outcomes included assessment of patient satisfaction (quality of life and pain felt during the injection) and product tolerance. Data were collected at two time points (one for the first formulation group and one for the second formulation group) through paper questionnaires administered to physicians, patients and nurses including a visual analog scale (VAS) from 0 (unsatisfied) to 10 (very satisfied).

RESULTS

Results showed that overall nurse satisfaction improved from 5.3 (95% CI 4.9-5.8) with the previous formulation to 7.5 (95% CI 7-7.9) with the new formulation (p < 0.0001). Regarding secondary outcomes, the simplicity of the injection increased (84% for the previous formulation and 94% for the new formulation) and the purge problem disappeared (36% for the previous formulation and 4% for the new formulation).

CONCLUSION

The improvement due to the new formulation of Sandostatin LAR^® was reported in terms of handling, ease of use and overall nurse satisfaction. The new formulation greatly reduced treatment administration problems associated with the previous formulation, while maintaining low injection site pain and an equivalent safety profile in both indications.

Patient-centered assessment on disease burden, quality of life, and treatment satisfaction associated with acromegaly

The study aimed to assess the economic burden, health-related quality of life (HRQoL), and acromegaly treatment satisfaction in the USA. A web-based, cross-sectional survey was distributed to members of Acromegaly Community. Data related to comorbidities, treatment patterns, and treatment satisfaction were collected. The costs over the past 3 months included out-of-pocket cost, sick leave, leave of absence, direct loss of job due to acromegaly, unemployment, assistance to perform household chores, and family member loss of income. The HRQoL was assessed by Acromegaly Quality of Life (AcroQoL) and EQ-5D-3L questionnaires. Among 106 patients who completed the survey (mean age: 46 years, female: 76.4%), 44.3% presented with ≥5 comorbidities, and 90.6% reporting acromegaly-related symptoms. Compared with the low-symptom group 0-3 (n=41), the 4+ symptoms group (n=65) was more likely to have depression (OR=2.3, 95% CI 1.1 to 5.2) and cardiovascular disease (OR=5.8, 95% CI 2.0 to 16.7), and experienced higher costs (loss of job: $8874 vs $1717, P=0.02; unemployment disability: $17,102 vs $429, P=0.003; household chores: $2160 vs $932, P=0.0003; family members' income loss: $692 vs $122, P=0.03). The high-symptom group had lower HRQoL scores, compared with the low-symptom group (EQ-5D-3L: 0.53 vs 0.75, P<0.0001; AcroQoL: 27 vs 56, P<0.0001). Only 55.7% among patients requiring injections for acromegaly were satisfied. Patients with acromegaly who presented with multiple acromegaly-related symptoms were evidenced to have experienced higher economic burden and poorer quality of life than patients with the same diagnosis but fewer symptoms. The low rate of treatment satisfaction warrants need for further studies.

Quality of life (QoL) impairments in patients with a pituitary adenoma: a systematic review of QoL studies

PURPOSE

Pituitary adenomas give rise to physical and psychological symptoms, which may persist after biochemical cure. Growing attention has been paid to quality of life (QoL) in these patients. We aimed to systematically analyze QoL assessment methods and QoL outcome in these patients.

METHODS

We conducted a systematic literature search up to January 2014 in PubMed, Web of Knowledge, PsycInfo and EMBASE.

RESULTS

102 papers assessing QoL in patients with a pituitary adenoma were included. In clinical (original) studies in which QoL was the primary outcome parameter (n = 54), 19 studies combined a generic questionnaire with a disease-specific questionnaire. QoL was found to be impaired in patients with active disease relative to controls, and generally improved during biochemical cure. However, no normalization occurred, with patients with remitted Cushing's disease demonstrating the smallest improvement. Somatic factors (e.g., hypopituitarism, sleep characteristics), psychological factors (illness perceptions) and health care environment (rural vs. urban) were identified as influencing factors. Intervention studies (predominantly evaluating medical interventions) have been found to improve QoL.

CONCLUSIONS

The growing number of studies assessing QoL generally described the negative impact of pituitary adenomas. QoL research in this patient group could be further elaborated by the development of disease-specific questionnaires for prolactinoma and non-functioning adenoma, consequent use of generic and disease-specific questionnaires and using a long-term (longitudinal) follow-up. Surgical and pharmacological interventions improve but not normalize QoL. We postulate that there might be margin for further improvement of QoL, for instance by using psychosocial interventions, in addition to optimal medical treatment.
