Assessing how routes to diagnosis vary by the age of patients with cancer: a nationwide register-based cohort study in Denmark.

BACKGROUND: Older patients with cancer have poorer prognosis compared to younger patients. Moreover, prognosis is related to how cancer is identified, and where in the healthcare system patients present, i.e. routes to diagnosis (RtD). We investigated whether RtD varied by patients' age. METHODS: This population-based national cohort study used Danish registry data. Patients were categorized into age groups and eight mutually exclusive RtD. We employed multinomial logistic regressions adjusted for sex, region, diagnosis year, cohabitation, education, income, immigration status and comorbidities. Screened and non-screened patients were analysed separately. RESULTS: The study included 137,876 patients. Both younger and older patients with cancer were less likely to get diagnosed after a cancer patient pathways referral from primary care physician compared to middle-aged patients. Older patients were more likely to get diagnosed via unplanned admission, death certificate only, and outpatient admission compared to younger patients. The patterns were similar across comorbidity levels. CONCLUSIONS: RtD varied by age groups, and middle-aged patients were the most likely to get diagnosed after cancer patient pathways with referral from primary care. Emphasis should be put on raising clinicians' awareness of cancer being the underlying cause of symptoms in both younger patients and in older patients.

Safety, efficiency and health-related quality of telephone triage conducted by general practitioners, nurses, or physicians in out-of-hours primary care: a quasi-experimental study using the Assessment of Quality in Telephone Triage (AQTT) to assess audio-recorded telephone calls.

BACKGROUND: To explore and compare safety, efficiency, and health-related quality of telephone triage in out-of-hours primary care (OOH-PC) services performed by general practitioners (GPs), nurses using a computerised decision support system (CDSS), or physicians with different medical specialities. METHODS: Natural quasi-experimental cross-sectional study conducted in November and December 2016. We randomly selected 1294 audio-recorded telephone triage calls from two Danish OOH-PC services triaged by GPs (n = 423), nurses using CDSS (n = 430), or physicians with different medical specialities (n = 441). An assessment panel of 24 physicians used a validated assessment tool (Assessment of Quality in Telephone Triage - AQTT) to assess all telephone triage calls and measured health-related quality, safety, and efficiency of triage. RESULTS: The relative risk (RR) of poor quality was significantly lower for nurses compared to GPs in four out of ten items regarding identifying and uncovering of problems. For most items, the quality tended to be lowest for physicians with different medical specialities. Compared to calls triaged by GPs (reference), the risk of clinically relevant undertriage was significantly lower for nurses, while physicians with different medical specialties had a similar risk (GP: 7.3%, nurse: 3.7%, physician: 6.1%). The risk of clinically relevant overtriage was significantly higher for nurses (9.1%) and physicians with different medical specialities (8.2%) compared to GPs (4.3%). GPs had significantly shorter calls (mean: 2 min 57 s, SD: 105 s) than nurses (mean: 4 min 44 s, SD: 168 s). CONCLUSIONS: Our explorative study indicated that nurses using CDSS performed better than GPs in telephone triage on a large number of health-related items, had a lower level of clinically relevant undertriage, but were perceived less efficient. Calls triaged by physicians with different medical specialities were perceived less safe and less efficient compared to GPs. Differences in the organisation of telephone triage may influence the distribution of workload in primary and secondary OOH services. Future research could compare the long-term outcomes following a telephone call to OOH-PC related to safety and efficiency.

Quality of out-of-hours telephone triage by general practitioners and nurses: development and testing of the AQTT - an assessment tool measuring communication, patient safety and efficiency.

OBJECTIVE: To develop a valid and reliable assessment tool able to measure quality of communication, patient safety and efficiency in out-of-hours (OOH) telephone triage conducted by both general practitioners (GP) and nurses. DESIGN: The Dutch KERNset tool was translated into Danish and supplemented with items from other existing tools. Face validity, content validity and applicability in OOH telephone triage (OOH-TT) were secured through a two-round Delphi process involving relevant stakeholders. Forty-eight OOH patient contacts were assessed by 24 assessors in test-retest and inter-rater designs. SETTING: OOH-TT services in Denmark conducted by GPs, nurses or doctors with varying medical specialisation. PATIENTS: Audio-recorded OOH patient contacts. MAIN OUTCOME MEASURES: Test-retest and inter-rater reliability were analysed using ICCagreement, Fleiss' kappa and percent agreement. RESULTS: Major adaptations during the Delphi process were made. The 24-item assessment tool (Assessment of Quality in Telephone Triage - AQTT) measured communicative quality, health-related quality and four overall quality aspects. The test-retest ICCagreement reliability was good for the overall quality of communication (0.85), health-related quality (0.83), patient safety (0.81) and efficiency (0.77) and satisfactory when assessing specific aspects. Inter-rater reliability revealed reduced reliability in ICCagreement and in Fleiss' kappa. Percent agreement revealed satisfactory agreements when differentiating between 'poor' and 'sufficient' quality). CONCLUSION: The AQTT demonstrated high face, content and construct validity, satisfactory test-retest reliability, reduced inter-rater reliability, but satisfactory percent agreement when differentiating between 'poor' and 'sufficient' quality. The AQTT was found feasible and clinically relevant for assessing the quality of GP- and nurse-led OOH-TT. KEYPOINTS Comparative knowledge is sparse regarding quality of out-of-hours telephone triage conducted by general practitioners and nurses. The assessment tool (AQTT) enables assessment of quality in OOH telephone triage conducted by nurses and general practitioners AQTT is feasible and clinically relevant for assessment of communication, patient safety and efficiency. AQTT can be used to identify areas for improvement in telephone triage.

Non-participation in breast cancer screening for women with chronic diseases and multimorbidity: a population-based cohort study.

BACKGROUND: Chronic diseases and multimorbidity are common in western countries and associated with increased breast cancer mortality. This study aims to investigate non-participation in breast cancer screening among women with chronic diseases and multimorbidity and the role of time in this association. METHOD: This population-based cohort study used regional and national registries. Women who were invited to the first breast cancer screening round in the Central Denmark Region in 2008-09 were included (n = 149,234). Selected chronic diseases and multimorbidity were assessed up to 10 years before the screening date. Prevalence ratios (PR) were used as an association measure. RESULTS: The results indicated that women with at least one chronic condition were significantly more likely not to participate in breast cancer screening. In adjusted analysis, a significantly higher likelihood of non-participation was found for women with cancer (PR = 1.50, 95% CI: 1.40-1.60), mental illness (PR = 1.51, 95% CI: 1.42-1.60), chronic obstructive pulmonary disease (PR = 1.51, 95% CI: 1.42-1.62), neurological disorders (PR = 1.24, 95% CI: 1.12-1.37) and kidney disease (PR = 1.70, 95% CI 1.49-1.94), whereas women with chronic bowel disease (PR = 0.75, 95% CI 0.65-0.88) were more likely to participate than women without these disease. Multimorbidity was associated with increased non-participation likelihood. E.g. having 3 or more diseases was associated with 58% increased non-participation likelihood (95% CI: 27-96%). Higher non-participation was also observed for women with severe multimorbidity (PR = 1.53, 95% CI: 1.23-1.90) and mental-physical multimorbidity (PR = 1.54, 95% CI: 1.36-1.75). CONCLUSION: In conclusion, we found a strong association between non-participation in breast cancer screening for some chronic diseases and for multimorbidity. The highest propensity not to participate was observed for women with hospital contacts related to the chronic disease in the period closest to the screening date.

Heart ischaemia-reperfusion induces local up-regulation of vasoconstrictor endothelin ETB receptors in rat coronary arteries downstream of occlusion.

BACKGROUND AND PURPOSE: Endothelins act via two receptor subtypes, ETA and ETB . Under physiological conditions in coronary arteries, ETA receptors expressed in smooth muscle cells mediate vasoconstriction whereas ETB receptors mainly found in endothelial cells mediate vasorelaxation. However, under pathophysiological conditions, ETB receptors may also be expressed in vascular smooth muscle cells mediating vasoconstriction. Here, we have investigated whether vasoconstrictor ETB receptors are up-regulated in coronary arteries after experimental myocardial ischaemia in rats. EXPERIMENTAL APPROACH: Male Sprague-Dawley rats were subjected to either heart ischaemia-reperfusion (15 min ischaemia and 22 h reperfusion), permanent ischaemia (22 h) by ligation of the left anterior descending coronary artery, or sham operation. Using wire myography, the endothelin receptor subtypes mediating vasoconstriction were examined in isolated segments of the left anterior descending and the non-ligated septal coronary arteries. Endothelin receptor-mediated vasoconstriction was examined with cumulative administration of sarafotoxin 6c (ETB receptor agonist) and endothelin-1 (with or without ETA or ETB receptor blockade). The distribution of ETB receptors was localized with immunohistochemistry and quantified by Western blot. KEY RESULTS: Endothelin ETB receptor-mediated vasoconstriction and receptor protein levels were significantly augmented in coronary arteries situated downstream of the occlusion after ischaemia-reperfusion compared with non-ischaemic arteries. In contrast, the ETA receptor-mediated vasoconstriction was unaltered in all groups. CONCLUSIONS AND IMPLICATIONS: Ischaemia-reperfusion induced local up-regulation of ETB receptors in the smooth muscle cells of coronary arteries in the post-ischaemic area. In contrast, in non-ischaemic areas, ETB receptor function was unaltered.

Distance to screening site and non-participation in screening for breast cancer: a population-based study.

BACKGROUND: In population-based breast cancer screening programmes, the geographical distance to the screening site may influence a woman's propensity to participate. The aim of this study was to analyse the effect driving distance to the screening unit had on women's participation in a breast cancer screening programme. METHODS: All women invited to the first round of breast cancer screening in the Central Denmark Region were eligible for inclusion (n = 149,234). Information on participation was collected from a regional administrative database. The shortest road distance between each woman's residence and her affiliated screening site was assessed using Network Analyst, ArcGIS. RESULTS: The unadjusted association between distance and non-participation formed a J-shape curve. Adjustment for socio-demographic characteristics caused the J-shape to disappear, and the probability of non-attendance rose with longer distance to the screening site but flattened after ~45 km. Women without access to a vehicle had a higher risk of non-participation than women with access to a vehicle. CONCLUSIONS: A long road distance to the screening site was associated with an increased risk of non-participation. Women without access to a vehicle were at higher risk of non-participation than women who had access to a vehicle.

Failure to investigate anaesthetic anaphylaxis resulting in a preventable second anaphylactic reaction.

We present a case of anaphylaxis to suxamethonium and/or vecuronium in a patient who had previously suffered an anaphylactic reaction, presumably to rocuronium. The patient had not been referred for formal allergy testing after the first anaphylactic reaction. Subsequent formal allergy testing revealed sensitivities to suxamethonium, rocuronium and vecuronium. Her next anaesthetic, using cisatracurium, was uneventful. It is recommended that all patients with suspected perioperative anaphylaxis are referred for testing. This is the responsibility of the anaesthetist. Particular caution should be used with suspected neuromuscular blocking drug allergy as cross-reactivity is common and not predictable by drug structure.

Sexuality and body image in long-term survivors of testicular cancer.

OBJECTIVE: This study explores sexual function and the influence of different treatment modalities on sexual function and body image among long-term survivors of testicular cancer (TCSs). METHODS: A long-term follow-up assessment of all testicular cancer patients treated at Aarhus University Hospital, Denmark, from 1990 to 2000 was conducted. A total of 401 survivors (mean age: 46.6years; response rate: 66%) completed questionnaires concerning sexuality and changes in body image. Based on the treatment received, patients were categorised into one of four groups: surveillance, radiotherapy, chemotherapy, or chemotherapy supplemented with retroperitoneal lymph node dissection (RPLND). RESULTS: Sexual dysfunctions were reported: 24% reduced sexual interest, 43% reduced sexual activity, 14% reduced sexual enjoyment, 18% erectile dysfunction, 7% ejaculatory problems and 3% increased sexual discomfort. Seventeen percent of the long-term TCSs reported changes in body image, and this was significantly associated with all six parameters of sexual dysfunction. When comparing treatments, only the RPLND procedure was associated with sexual dysfunction in the form of ejaculatory dysfunction. CONCLUSION: Apart from RPLND, which was associated with ejaculatory dysfunction, treatment strategies for testicular cancer appeared not to influence sexual dysfunction. The level of erectile dysfunction seen in this sample of TCSs seemed to be higher than the level observed in the general male population and high levels of erectile dysfunction were associated with negative changes in body image. The results suggest that changes in body image are of importance when explaining the variation in sexual dysfunctions, but further prospective studies are needed to clarify this issue.

Social support, gender and patient delay.

BACKGROUND: The purpose of this study was to examine the relationship between perceived social support and patient delay (PD) among female and male cancer patients. METHODS: A population-based study with register-sampled cancer patients was designed. Patient delay was defined as the time interval between the patient's experience of the first symptom and the first contact with a health-care professional. Both dates were provided by the patients (n=910). The patients completed a purpose-designed questionnaire, which assessed the patient's perceptions of how the partner reacted ('Partner Avoidance' and 'Partner Support') and how others in the social network responded ('Other Avoidance' and 'Other Support') to the patient's worries about the symptoms. The associations between the social support subscales and PD were analysed separately for men and women. RESULTS: In female patients, Partner Support and Other Support were associated with shorter PD, whereas Other Avoidance was associated with longer PD. In the multivariate analysis, Other Avoidance remained associated with longer PD. Moreover, disclosure of symptoms to someone reduced the likelihood of a long PD in female patients. In male patients, none of the social support scales significantly increased or decreased the risk of a long PD in the univariate analysis, but Partner Support significantly decreased risk of a long PD in the multivariate analysis. CONCLUSIONS: The results of this study suggest that social support and avoidance from network members influence length of PD differently in male and female cancer patients. This gender difference may explain previous mixed findings obtained in this field.
