Development and validation of the Multimorbidity Treatment Burden Questionnaire (MTBQ)
OBJECTIVE: To develop and validate a new scale to assess treatment burden (the effort of looking after one's health) for patients with multimorbidity. DESIGN: Mixed-methods. SETTING: UK primary care. PARTICIPANTS: Content of the Multimorbidity Treatment Burden Questionnaire (MTBQ) was based on a literature review and views from a patient and public involvement group. Face validity was assessed through cognitive interviews. The scale was piloted and the final version was tested in 1546 adults with multimorbidity (mean age 71 years) who took part in the 3D Study, a cluster randomised controlled trial. For each question, we examined the proportion of missing data and the distribution of responses. Factor analysis, Cronbach's alpha, Spearman's rank correlations and longitudinal regression assessed dimensional structure, internal consistency reliability, construct validity and responsiveness, respectively. We assessed interpretability by grouping the global MTBQ scores into zero and tertiles (>0) and comparing participant characteristics across these categories. RESULTS: Cognitive interviews found good acceptability and content validity. Factor analysis supported a one-factor solution. Cronbach's alpha was 0.83, indicating internal consistency reliability. The MTBQ score had a positive association with a comparator treatment burden scale (rs 0.58, P<0.0001) and with self-reported disease burden (rs 0.43, P<0.0001), and a negative association with quality of life (rs-0.36, P<0.0001) and self-rated health (rs-0.36, P<0.0001). Female participants, younger participants and participants with mental health conditions were more likely to have high treatment burden scores. Changes in MTBQ score over 9-month follow-up were associated, as expected, with changes in measures of quality of life (EuroQol five dimensions, five level questionnaire) and patient-centred care (Patient Assessment of Chronic Illness Care). CONCLUSION: The MTBQ is a 10-item measure of treatment burden for patients with multimorbidity that has demonstrated good content validity, construct validity, reliability and responsiveness. It is a useful research tool for assessing the impact of interventions on treatment burden. TRIAL REGISTRATION NUMBER: ISRCTN06180958
Determinants of obesity and perception of weight in hypertensive patients in rural South Africa
Objective: The objective of the study was to identify factors associated with being overweight or obese, and perceptions of weight by hypertensive patients living in rural South Africa.Design: This was a nested cross-sectional study.Setting: The setting was primary healthcare clinics close to Manguzi Hospital, KwaZulu-Natal.Subjects: Subjects were 109 males and 391 females, prescribed at least one antihypertensive medication aged ≥ 18 years.Outcome measures: The primary outcome measure was body mass index (BMI) ≥ 25 kg/m2. The secondary outcome measure was recognition of being overweight by those with a BMI ≥ 25 kg/m2.Results: The mean age was 58 years. Three hundred and ninety-one (78%) participants were female, and the majority had never been to school or had attended primary school only. Three hundred and eleven (62%) participants were overweight or obese, with a BMI ≥ 25 kg/m2. Factors associated with being overweight or obese included having high cholesterol [adjusted odds ratio (OR) 10.62, 95% confidence interval (CI): 1.22-92.4, p-value 0.032], and having never smoked (adjusted OR 3.22, 95% CI: 1.38-7.52, p-value 0.007. Human immunodeficiency virus (HIV) was associated with a lower risk of being overweight or obese (adjusted OR 0.52 for BMI ≥ 25, 95% CI: 0.31-0.89, p-value < 0.0001). Only 12% of participants who were overweight or obese perceived that they were overweight. Participants with a BMI ≥ 25 kg/m2 were most likely to recognise they were overweight if they had high cholesterol, diabetes or HIV.Conclusion: Almost two thirds of participants were overweight or obese, and of these, only 12% perceived that they were overweight. Educating patients about obesity, particularly when they have other cardiovascular risk factors such as hypertension, is of public health importance.Keywords: obesity, overweight, weight perception, hypertension, body mass inde
A new collaborative model of primary care research:could it provide trainees and clinicians with more opportunities to get involved?
Deprescribing:a primary care perspective
Polypharmacy is an increasing and global issue affecting primary care. Although sometimes appropriate, polypharmacy can also be problematic, leading to a range of adverse consequences. Deprescribing is the process of supervised withdrawal of an inappropriate medication and has the potential to reduce some of the problems associated with polypharmacy. It is a complex and sensitive process. We examine the issue of deprescribing from the perspective of primary care. Key steps in the deprescribing process are a review of medications and corresponding indications, consideration of harms, assessment of eligibility for discontinuation, prioritisation of medications and implementation of a stopping plan with appropriate monitoring. Patient involvement is a key feature of this process. Deprescribing should be considered in the context of end-of-life care and medication safety, but approaches are also required to identify other situations where deprescribing is appropriate. General practitioners are well positioned to facilitate deprescribing, usually through formal medication review, with decisions informed by a range of other healthcare professionals. Guidelines are available that help guide these processes. A range of studies have explored attitudes towards deprescribing; patients are generally supportive of the concept, although clinician views are varied. The successful implementation of deprescribing strategies still requires important patient and clinician barriers to be overcome, and clinical trial evidence of effectiveness and safety is essential
International prescribing patterns and polypharmacy in older people with advanced chronic kidney disease:results from the European Quality Study
Adaptation and validation of a German version of the Multimorbidity Treatment Burden Questionnaire
BACKGROUND: Patients with multiple long-term conditions often face a variety of challenges arising from the requirements of their health care. Knowledge of perceived treatment burden is crucial for optimizing treatment. In this study, we aimed to create a German version of the Multimorbidity Treatment Burden Questionnaire (MTBQ) and to evaluate its validity. METHODS: The steps to translate the MTBQ included forward/back translation, cognitive interviews (n = 6) and a pilot test (n = 7). Psychometric properties of the scale were assessed in a cross-sectional survey with primary care patients aged 65 and older with at least 3 long-term conditions (n = 344). We examined the distribution of responses, dimensionality, internal reliability and construct validity. RESULTS: Cognitive interviewing and piloting led to minor modifications and showed overall good face validity and acceptability. As expected, we observed a positively skewed response distribution for all items. Reliability was acceptable with McDonald’s omega = 0.71. Factor analysis suggested one common factor while model fit indices were inconclusive. Predefined hypotheses regarding the construct validity were supported by negative associations between treatment burden and health-related quality of life, self-rated health, social support, patient activation and medication adherence, and positive associations between treatment burden and number of comorbidities. Treatment burden was found to be higher in female participants (Mdn(1) = 6.82, Mdn(2) = 4.55; U = 11,729, p = 0.001) and participants with mental health diagnoses (Mdn(1) = 9.10, Mdn(2) = 4.55; U = 3172, p = 0.024). CONCLUSIONS: The German MTBQ exhibited good psychometric properties and can be used to assess the perceived treatment burden of patients with multimorbidity.
