Prognosis of cancer in persons with infrequent consultations in general practice: A population-based cohort study

Multiple myeloma: unplanned diagnostic pathways and association with risk factors and survival - a nationwide register-based cohort study in Denmark

BACKGROUND

Multiple myeloma often presents with vague and non-specific symptoms. Many patients are diagnosed in unplanned rather than elective (planned) diagnostic pathways. This study investigates the diagnosis of multiple myeloma in unplanned pathways and the association with patient characteristics, disease profile, and survival.

METHODS

We conducted a nationwide register-based study, including all patients diagnosed with multiple myeloma in Denmark in 2014-2018. Patients were categorised as diagnosed in an unplanned pathway if registered with an acute admission within 30 days prior to the multiple myeloma diagnosis and no other previously registered pathway to this diagnosis. Unplanned pathways were compared to all other pathways combined.

RESULTS

We included 2,213 patients diagnosed with multiple myeloma, hereof 32% diagnosed in an unplanned pathway. Comorbidity, no prior cancer diagnosis, a history of few visits to the general practitioner (GP), multiple myeloma complications at diagnosis, high-risk cytogenetics, and advanced cancer stage were associated with a higher probability of being diagnosed in an unplanned pathway. For example, 24.4% (95% confidence interval (CI): 21.8-27.0) of patients with low comorbidity (Charlson Comorbidity Index (CCI) score 0) were diagnosed in an unplanned pathway as were 50.9% (95% CI: 45.6-56.1) of patients with high comorbidity (CCI score 3+). For patients with dialysis need at the time of diagnosis the probability was 66.0% (95% CI 54.2-77.8) and 30.9% (95% CI: 28.9-32.9) for patients with no dialysis need. Patients diagnosed in an unplanned pathway had inferior survival (hazard ratio 1.44 (95% CI: 1.26-1.64)). However, this association was not seen in analyses restricted to patients surviving for more than three years.

CONCLUSIONS

High comorbidity level, few usual GP visits, advanced disease status at diagnosis, and complications were associated with diagnosis in an unplanned pathway. Further, patients diagnosed in an unplanned pathway had inferior survival. Promoting earlier diagnosis and preventing unplanned pathways may help improve survival in multiple myeloma.

Psychiatric disorders and the cancer diagnostic process in general practice: a combined questionnaire and register study exploring the patients' experiences in Denmark

OBJECTIVE

Patients with psychiatric disorders are at risk of experiencing suboptimal cancer diagnostics and treatment. This study investigates how this patient group perceives the cancer diagnostic process in general practice.

DESIGN

Cross-sectional study using questionnaire and register data.

SETTING

General practice in Denmark.

SUBJECTS

Patients diagnosed with cancer in late 2016 completed a questionnaire about their experiences with their general practitioner (GP) in the cancer diagnostic process (n = 3411). Information on pre-existing psychiatric disorders was obtained from register data on psychiatric hospital contacts and primary care treated psychiatric disorders through psychotropic medications. Logistic regression was used to analyse the association between psychiatric disorders and the patients' experiences.

MAIN OUTCOME MEASURES

Patients' experiences, including cancer worry, feeling being taken seriously, and the perceived time between booking an appointment and the first GP consultation.[Box: see text].

RESULTS

A total of 13% of patients had an indication of a psychiatric disorder. This group more often perceived the time interval as too short between the first booking of a consultation and the first GP consultation. Patients with primary care treated psychiatric disorders were more likely to worry about cancer at the first presentation and to share this concern with their GP compared with patients without psychiatric disorders. We observed no statistically significant association between patients with psychiatric disorders and perceiving the waiting time to referral from general practice, being taken seriously, trust in the GP's abilities, and the patients' knowledge of the process following the GP referral.

CONCLUSION

The patients' experiences with the cancer diagnostic process in general practice did not vary largely between patients with and without psychiatric disorders. Worrying about cancer may be a particular concern for patients with primary care treated psychiatric disorders.

Improving communication between the general practitioner and the oncologist: a key role in coordinating care for patients suffering from cancer

Background

Patients suffering from cancers are increasingly numerous in general practice consultations. The General Practitioner (GP) should be at the heart of the management of patients. Several studies have examined the perceptions of GPs confronted with the patient suffering from cancer and the relationships of GPs with oncologists, but few studies have focused on the patients’ perspective. We studied the three-way relationship between the oncologist, the GP, and the patient, from the patient’s point of view.

Methods

A questionnaire validated by a group consisting of GPs, oncologists, nurses, an epidemiologist and quality analyst, was administered over a three-week period to patients suffering from cancer receiving chemotherapy in a day hospital.

Results

The analysis was based on 403 questionnaires. Patients had confidence in the GP’s knowledge of oncology in 88% of cases; 49% consulted their GP for pain, 15% for cancer-related advice, and 44% in emergencies. Perceived good GP/oncologist communication led patients to turn increasingly to their GP for cancer-related consultations (RR = 1.14; p = 0.01) and gave patients confidence in the GP’s ability to manage cancer-related problems (RR = 1.30; p < 0.01). Mention by the oncologist of the GP’s role increased the consultations for complications (RR = 1.82; p < 0.01) as well as recourse to the GP in an emergency (RR = 1.35; p < 0.01).

Conclusion

Patients suffering from cancer considered that the GP was competent, but did not often consult their GP for cancer-related problems. There is a discrepancy between patients’ beliefs and their behaviour. When the oncologist spoke to patients of the GP’s role, patients had recourse to their GP more often. Systematically integrating a GP consultation to conclude cancer diagnosis disclosure, could improve management and care coordination.

Characteristics of customary non-attenders in general practice who are diagnosed with cancer: A cross-sectional study in Denmark

OBJECTIVE

This study aimed to explore individual and structural factors in patients with cancer and their potential association with customary non-attendance in general practice.

MATERIALS AND METHODS

We conducted a population-based cross-sectional study of all patients aged 50-89 years who were diagnosed with an incident cancer in 2009-2013 in Denmark. We investigated associations between being a customary non-attender (defined as having no consultations in general practice in the 19-36 months before diagnosis) and selected patient-related factors (demography, socioeconomic status), health-related factors (multimorbidity) and structural factors (urbanisation degree, list size of general practice and use of out-of-hours services) using logistic regression.

RESULTS

A total of 123,943 cancer patients were included; 11,567 (9.3%) of these were non-attenders. Non-attendance was associated with being more than 70 years of age, being single, having short or long education and being financially affluent. Non-attendance was rarely seen in cancer patients with (multi)morbidity, in individuals living in an area with 2,000-99,999 inhabitants and in individuals having contact with the out-of-hours services.

CONCLUSION

Specific groups of cancer patients were more often customary non-attenders in general practice. General practice may need to reach out more directly to these patients to ensure more timely cancer diagnosis.

Association between GPs' suspicion of cancer and patients' usual consultation pattern in primary care: a cross-sectional study

BACKGROUND

Patients who rarely consult a GP in the 19-36 months before a cancer diagnosis have more advanced cancer at diagnosis and a worse prognosis. To ensure more timely diagnosis of cancer, the GP should suspect cancer as early as possible.

AIM

To investigate the GP's suspicion of cancer according to the patient with cancer's usual consultation pattern in general practice.

DESIGN AND SETTING

A cross-sectional study based on survey data from general practice of 3985 Danish patients diagnosed with cancer from May 2010 to August 2010, and linked to national register data.

METHOD

Using logistic regression analysis with restricted cubic splines, the odds ratio (OR) of the GP to suspect cancer as a function of the patient's number of face-to-face consultations with the GP in the 19-36 months before a cancer diagnosis was estimated.

RESULTS

GPs' cancer suspicion decreased with higher usual consultation frequency in general practice. A significant decreasing trend in ORs for cancer suspicion was seen across usual consultation categories overall (P<0.001) and for each sex (males: P<0.05; females: P<0.05). GPs' cancer suspicion was lower in patients aged <55 years in both rare and frequent attenders compared with average attenders.

CONCLUSION

GPs suspect cancer more often in rare attenders ≥55 years. GPs' cancer suspicion was lower in younger patients (<55 years), in both rare and frequent attenders. GPs should be aware of possible missed opportunities for cancer diagnosis in young attenders and use safety netting to reduce the risk of missing a cancer diagnosis.
