Associations between patients' adherence and GPs' attitudes towards risk, statin therapy and management of non-adherence--a survey and register-based study.

BACKGROUND: Previous studies suggest that doctors' personal lifestyle, risk taking personality and beliefs about risk reducing therapies may affect their clinical decision-making. Whether such factors are further associated with patients' adherence with medication is largely unknown. OBJECTIVE: To estimate associations between GPs' attitudes towards risk, statin therapy and management of non-adherence and their patients' adherence, and to identify subgroups of GPs with poor patient adherence. METHODS: All Danish GPs were invited to participate in an online survey. We asked whether they regarded statin treatment as important, how they managed non-adherence and whether non-adherence annoyed them. The Jackson Personality Inventory-revised was used to measure risk attitude. The GPs' responses were linked to register data on their patients' redeemed statin prescriptions. Mixed effect logistic regression was used to estimate associations between patient adherence and GPs' attitudes. Adherence was estimated by the proportion of days covered in a 1-year period using an 80% cut-off. RESULTS: We received responses from 1398 GPs (42.2%) who initiated statin therapy in 12 192 patients during the study period. In total 6590 (54.1%) of these patients were adherent. Patients who had GPs rarely assessing their treatment adherence were less likely to be adherent than those who had GPs assessing their patients' treatment adherence now and then, odds ratio (OR) 0.86 [confidence interval (CI) 0.77-0.96]. No other associations were found between patients' adherence and GPs' attitudes. CONCLUSIONS: Our findings suggest that GPs' attitudes to risk, statin therapy or management of non-adherence are not significantly associated with their patients' adherence.

General practitioners' home visit tendency and readmission-free survival after COPD hospitalisation: a Danish nationwide cohort study.

BACKGROUND: The tendency of general practitioners (GPs) to conduct home visits is considered an important aspect of practices' accessibility and quality of care. AIMS: To investigate whether GPs' tendency to conduct home visits affects 30-day readmission or death after hospitalisation with chronic obstructive pulmonary disease. METHODS: All Danish patients first-time hospitalised with COPD during the years 2006-2008 were identified. The association between the GP's tendency to conduct home visits and the time from hospital discharge until death or all-cause readmission was analysed by means of Cox regression adjusted for multiple patient and practice characteristics. RESULTS: The study included 14,425 patients listed with 1,389 general practices. Approximately 31% of the patients received a home visit during the year preceding their first COPD hospitalisation, and within 30 days after discharge 19% had been readmitted and 1.6% had died without readmission. A U-shaped dose-response relationship was found between GP home visit tendency and readmission-free survival. The lowest adjusted risk of readmission or death was recorded among patients who were listed with a general practice in which >20-30% of other listed first-time COPD-hospitalised patients had received a home visit. The risk was higher if either 0% (hazard rate ratio 1.18 (1.01-1.37)) or >60% (hazard rate ratio 1.23 (1.04-1.44)) of the patients had been visited. CONCLUSION: A moderate GP tendency to conduct home visits is associated with the lowest 30-day risk of COPD readmission or death. A GP's tendency to conduct home visits should not be used as a unidirectional indicator of the ability to prevent COPD hospital readmissions.

Strategies for discontinuation of proton pump inhibitors: a systematic review.

PURPOSE: Proton pump inhibitors (PPIs) are considered to be overprescribed. Consensus on how to attempt discontinuation is, however, lacking. We therefore conducted a systematic review of clinical studies on discontinuation of PPIs. METHODS: Systematic review based on clinical studies investigating discontinuation strategies and discontinuation rates for users of antisecretory medication judged eligible for withdrawal. The databases Medline, Embase and Cochrane Library were searched to December 2013 using the terms antisecretory, anti-ulcer, PPI, acid suppressant, discontinuation, step-down, step down, cessation, tapering, withdrawal and withhold. Search terms were used either singularly or in combination. Papers written in English or Scandinavian were included. Concurrent hand searching was undertaken to pursue references of references. The website ClinicalTrials.gov was searched for unpublished results and ongoing studies. A total of 371 abstracts were scrutinized to determine relevancy. RESULTS: The thorough search resulted in six clinical studies on strategies for discontinuation of PPIs. All discontinuation regimens used in the studies differed, and several interventions have been tested in order to decrease use of PPIs. Discontinuations were reported across all studies ranging from 14% to 64% without deteriorating symptom control. Tapering seems to be a more effective discontinuation strategy than abrupt discontinuation. CONCLUSION: Discontinuation of PPIs is feasible in a clinical setting, and a substantial number of the patients treated without a clear indication can safely reduce or discontinue treatment. Tapering seems to be the most effective way of doing this.

Multimorbidity and blood pressure control in 37 651 hypertensive patients from Danish general practice.

BACKGROUND: Patients with hypertension are primarily treated in general practice. However, major studies of patients with hypertension are rarely based on populations from primary care. Knowledge of blood pressure (BP) control rates in patients with diabetes and/or cardiovascular diseases (CVDs), who have additional comorbidities, is lacking. We aimed to investigate the association of comorbidities with BP control using a large cohort of hypertensive patients from primary care practices. METHODS AND RESULTS: Using the Danish General Practice Database, we included 37 651 patients with hypertension from 231 general practices in Denmark. Recommended BP control was defined as BP <140/90 mm Hg in general and <130/80 mm Hg in patients with diabetes. The overall control rate was 33.2% (95% CI: 32.7 to 33.7). Only 16.5% (95% CI: 15.8 to 17.3) of patients with diabetes achieved BP control, whereas control rates ranged from 42.9% to 51.4% for patients with ischemic heart diseases or cerebrovascular or peripheral vascular diseases. A diagnosis of cardiac heart failure in addition to diabetes and/or CVD was associated with higher BP control rates, compared with men and women having only diabetes and/or CVD. A diagnosis of asthma in addition to diabetes and CVD was associated with higher BP control rates in men. CONCLUSION: In Danish general practice, only 1 of 3 patients diagnosed with hypertension had a BP below target. BP control rates differ substantially within comorbidities. Other serious comorbidities in addition to diabetes and/or CVD were not associated with lower BP control rates; on the contrary, in some cases the BP control rates were higher when the patient was diagnosed with other serious comorbidities in addition to diabetes and/or CVD.
