    • Objective: The present study aimed to describe contact made by the elderly to Sweden's nationwide medical helpline, Healthcare Guide 1177 by Phone (HGP). Other objectives were to study potential gender differences and the association between different HGP referral levels and acute visits to hospital-based emergency departments and acute visits to primary care centres. Design: De-identified data from recorded calls to HGP was extracted for analysis (n=7477 for the oldest age group). Information about acute visits to emergency departments and to primary care reception was extracted from the patient administration system.Setting: Vasterbotten County, Sweden.Subjects: Patients over 80 years.Main outcome measures: Calling and visiting frequencies for different age groups as well as reasons for contact and individual recommendations. Results: The utilisation rate of the telephone advice service for the oldest age group was high, with an incidence rate of 533 per 1000 person-years. Women had a 1.17 times higher incidence rate compared with men. The most common reason for contact was drug-related questions (17% of all contacts). Calls that were recommended to care by a medical specialist correlated with total emergency department visits (r=0.30, p<0.05) and calls that were given advice correlated with acute primary healthcare visits (r=0.38, p=0.005). Conclusion: The high utilisation of the telephone advice service by the elderly gives the telephone advice service a unique ability to function as a gatekeeper to further healthcare. Our data suggest that with the telephone advice service's present guidelines, a significant proportion of all calls are being directed to further medical help. The high frequency of drug-related questions raises concerns about the elderly's medication regimens.

  • 2015
  • Ingår i: Journal of hypertension. - : Ovid Technologies (Wolters Kluwer Health). - 0263-6352 .- 1473-5598. ; 33 Suppl 1
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • OBJECTIVE: To investigate whether treatment with thiazide diuretics reduces the risk of osteoporotic fractures in hypertensive patients in primary health care. Further we aimed to examine the impact of duration of thiazide use, the consequences of discontinuation of use and effect-modifications by gender. DESIGN AND METHOD: This retrospective cohort study includes 60 893 individuals, diagnosed with hypertension during 2001-2008 included in the Swedish Primary Care Cardiovascular Database. All patients were followed from a fixed baseline (1 Jan 2006, or the date the patient received their first diagnosis of hypertension if that date came later) until they had an incident osteoporotic fracture, died, or reached the end of the study at 31 Dec 2012, whichever came first. Patients exposed to thiazide diuretics (dispensed drugs recorded through the Prescribed Drug Register) were compared with hypertensive patients never exposed to thiazides. RESULTS: During follow up 2421 osteoporotic fractures occurred. Current use of thiazide diuretics was found to be associated with significantly reduced risk of osteoporotic fractures (adjusted hazard ratios 0.88; 95% CI 0.81-0.97) independent of blood pressure level. In addition, risk appeared to decline with longer duration of use. In contrast, discontinuation of dispensed prescriptions of thiazides was associated with increased risk of osteoporotic fractures (HR 1.17; 95% CI 1.04-1.31).However, a trend towards attenuation of the increased risk with longer duration past treatment period was seen. When analyzing men and women separately similar results were seen, for both genders, although only statistically significant for men. CONCLUSIONS: In this large retrospective cohort study of hypertensive men and women from Sweden, we could identity a protective effect on osteoporotic fractures among current users of thiazide diuretic drugs independent of blood pressure level. However, the risk of fracture was found to be increased in patients shortly after discontinuation of treatment compared to patients never prescribed thiazide diuretic drugs. The reason for an augmented outcome on osteoporotic fractures among patients with former thiazide diuretic therapy needs to be further elucidated.

    • Objective. To describe the Swedish Primary Care Cardiovascular Database, SPCCD. Design. Longitudinal data from electronic medical records, linked to national registers. Setting. 48 primary healthcare centres in urban (south-western Stockholm) and rural (Skaraborg) regions in Sweden. Subjects. Patients diagnosed with hypertension 2001-2008. Main outcome measures. Blood pressure (BP) and impact of retrieval of data on BP levels, clinical characteristics, co-morbidity and pharmacological treatment. Results. The SPCCD contains 74 751 individuals, 56% women. Completeness of data ranged from >99% for drug prescriptions to 34% for smoking habits. BP was recorded in 98% of patients during 2001-2008 and in 63% in 2008. Mean BP based on the last recorded value in 2008 was 142 +/- 17/80 +/- 13 mmHg. Digit preference in BP measurements differed between the two regions, p < 0.001. Antihypertensive drugs were prescribed in primary healthcare to 88% of the patients in 2008; however, when all prescribers were included 96% purchased their drugs. Cardiovascular co-morbidity and diabetes mellitus were present in 28% and 22%, respectively. Conclusion. This large and representative database shows that there is room for improvement of BP control in Sweden. The SPCCD will provide a rich source for further research of hypertension and its complications.

  • Tidskriftsartikel (refereegranskat)abstract
    • Objective:To study temporal trends in hypertension treatment and control in Swedish primary care, in relation to clinical characteristics, comorbidity, and drug treatment.Materials and methods:Repeated cross-sectional analysis of 43239 hypertensive patients attending primary care in 2001-2002 and of 62407 patients in 2007-2008.Results:Mean blood pressure (BP) 2007-2008 was 143/79mmHg in women and 142/81mmHg in men. Cardiovascular comorbidity and diabetes were present in 13 and 15% of women, and in 18 and 20% of men. Overall BP reductions from 2001-2002 to 2007-2008 were 9.0/3.1mmHg; greater in women than men, with advancing age, and in patients with comorbidity (all P<0.001). Attainment of target BP (<140/90mmHg) increased from 24 and 26% in women and men (2001-2002) to 37 and 37% (2007-2008; all P<0.001). Most common drug classes in 2001-2002 were, in descending frequency, blockers, diuretics, and calcium channel blockers (both sexes), and in 2007-2008 blockers, diuretics, and angiotensin-converting enzyme inhibitors in women, and blockers, angiotensin-converting enzyme inhibitors, and diuretics in men. The number of drug classes/patient increased from 1.5 (2001-2002) to 1.8 (2007-2008; P<0.001) but remained low (1.7) in those above target BP.Conclusion:BP control in hypertensive patients attending Swedish primary care has improved over 5-7 years, and more so in high-risk groups. There is, however, room for improvement. In uncontrolled hypertension the combination of several drug classes remain low.

    • Purpose To assess drug adherence in patients treated with 3 antihypertensive drug classes, with both controlled and uncontrolled blood pressure and describe associated factors for nonadherence. Methods Patients with hypertension, without cardiovascular comorbidity, aged >30years treated with 3 antihypertensive drug classes were followed for 2years. Both patients with treatment resistant hypertension (TRH) and patients with controlled hypertension were included. Clinical data were derived from a primary care database. Pharmacy refill data from the Swedish Prescribed drug registry was used to calculate proportion of days covered (PDC). Patients with a PDC level80% were included. Results We found 5846 patients treated 3 antihypertensive drug classes, 3508 with TRH (blood pressure140/90), and 2338 with controlled blood pressure (<140/90mmHg). TRH patients were older (69.1 vs 65.8years, P<.0001) but had less diabetes (28.5 vs 31.7%, P<.009) compared with patients with controlled blood pressure. The proportion of patients with PDC80% declined with 11% during the first year in both groups. Having diabetes was associated with staying adherent at 1year (RR 0.82; 95% CI, 0.68-0.98) whilst being born outside Europe was associated with nonadherence at one and (RR 2.05; 95% CI, 1.49-2.82). ConclusionsPatients with multiple antihypertensive drug therapy had similar decline in adherence over time regardless of initial blood pressure control. Diabetes was associated with better adherence, which may imply that the structured caregiving of these patients enhances antihypertensive drug treatment.

  • 7b.02: The Association between Non-Steroidal Anti-Inflammatory Drugs and Blood Pressure Control in Hypertensive Patients and the Relation to Gender
  • 2015
  • Ingår i: Journal of hypertension. - : Ovid Technologies (Wolters Kluwer Health). - 0263-6352 .- 1473-5598. ; 33 Suppl 1
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • OBJECTIVE: Approximately 25% of hypertensive patients >65 years are treated for arthrosis, which is the most common cause of long term use of non-steroidal anti-inflammatory drugs (NSAID). NSAID inhibits prostaglandin synthesis and interacts with the renin angiotensin system. The objective of this study was to investigate if concomitant use of NSAID in hypertensive patients is associated with a lower possibility to reach target blood pressure <140/90 mm Hg, and to elucidate if there are gender differences regarding this matter.(Figure is included in full-text article.) DESIGN AND METHOD: : This cross-sectional cohort study includes 40825 patients with hypertension from the Swedish primary Care Cardiovascular Database (SPCCD) in 2007-2008. Patient characteristics, antihypertensive drug class, dispensations of NSAIDs, comorbidities and blood pressure measurements were analyzed. The proportion of days covered (PDC) with prescription was calculated in order to analyze the NSAID use and the PDC was grouped <50%, 50-80% and >80% of days covered with prescription during 180 days prior to the last blood pressure measurement. RESULTS: In all 6700 patients had at least one prescription of NSAID. Patients with NSAID were younger (67.9 +/- 11.2 vs 69.4 +/- 11.9 years, p < 0.0001), and more often female (63.2 vs 56.3%, p < 0.0001) with a diagnosis of musculoskeletal disease (20.8 vs 12.8%, p < 0.0001 and with no cardiovascular comorbidity (26.5 vs 32.1%, p < 0.0001). There was no difference in SBP between patients with and without NSAID (142 +/- 16, 142 +/- 17 mmHg respectively, ns). Patients with NSAID had a higher DBP (80 +/- 10, 79 +/- 10 mmHg, respectively p < 0.001). In a logistic regression model adjusted for age, smoking, cardiovascular comorbidity, antihypertensive drug class, education, and country of birth there was no difference in the proportion achieving target blood pressure in patients with and without concomitant use of NSAID irrespective of the PDC for NSAID users (figure 1). The results were similar in both genders. CONCLUSIONS: Concomitant use of NSAID in hypertensive patients does not seem to be associated with a higher blood pressure level. The use of NSAIDs is not associated with a reduced ability of achieving target blood pressure. Thus, hypertensive patients do not a priori need to be discouraged to use NSAID.

  • Ingår i: American Journal of Cardiology. - : Elsevier BV. - 0002-9149 .- 1879-1913. ; 122:1, s. 102-107
  • Tidskriftsartikel (refereegranskat)abstract
    • The relation between dyslipidemia and atrial fibrillation (AF) development is still controversial. To assess the impact of lipid profile on new-onset AF, we followed 51,020 primary-care hypertensive patients without AF at baseline. After a mean follow-up time of 3.5 years, AF occurred in 2,389 participants (4.7%). We evaluated the association between total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, and new-onset AF. In a Poisson regression model fully adjusted for common risk factors of AF, we found that 1.0 mmol/l (39 mg/dl) increase in total cholesterol was associated with 19% lower risk of new-onset AF (95% confidence interval [CI] 9% to 28%), and 1.0 mmol/l (39 mg/dl) increase in low-density lipoprotein cholesterol was associated with 16% lower risk of new-onset AF (95% CI 3% to 27%). Gender-specific Poisson regression analyses revealed that increase in total cholesterol by 1.0 mmol/l (39 mg/ dl) was found to be associated with lower risk of new-onset AF with 21% in men (95% CI 8% to 32%), and 18% in women (95% CI 1% to 31%). There was no association between high-density lipoprotein cholesterol or triglycerides and new-onset AF, neither in the whole population with respect to separate gender. In conclusion, in a large hypertensive population we found an inverse association between total cholesterol and new-onset AF for both men and women. Our results confirm previous reports of a dyslipidemia paradox, and extend these observations to the hypertensive population. (C) 2018 Elsevier Inc. All rights reserved.

  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Primary health care (PHC) is often the first point of contact when diagnosing colorectal cancer (CRC). Human limitations in processing large amounts of information warrant the use of machine learning as a diagnostic prediction tool for CRC. Aim: To develop a predictive model for identifying non-metastatic CRC (NMCRC) among PHC patients using diagnostic data analysed with machine learning. Design and setting: A case-control study containing data on PHC visits for 542 patients >18 years old diagnosed with NMCRC in the Vastra Gotaland Region, Sweden, during 2011, and 2,139 matched controls. Method: Stochastic gradient boosting (SGB) was used to construct a model for predicting the presence of NMCRC based on diagnostic codes from PHC consultations during the year before the date of cancer diagnosis and the total number of consultations. Variables with a normalised relative influence (NRI) >1% were considered having an important contribution to the model. Risks of having NMCRC were calculated using odds ratios of marginal effects. Results: Of the 361 variables used as predictors in the stochastic gradient boosting model, 184 had non-zero influence, with 16 variables having NRI >1% and a combined NRI of 63.3%. Variables representing anaemia and bleeding had a combined NRI of 27.6%. The model had a sensitivity of 73.3% and a specificity of 83.5%. Change in bowel habit had the highest odds ratios of marginal effects at 28.8. Conclusion: Machine learning is useful for identifying variables of importance for predicting NMCRC in PHC. Malignant diagnoses may be hidden behind benign symptoms such as haemorrhoids. 2023 The Author(s). Published by Elsevier Ltd.
