Pain management at the end of life: A comparative study of cancer, dementia, and chronic obstructive pulmonary disease patients

Background: Limited data exist concerning the unique pain characteristics of patients with non-cancer terminal diseases referred for inpatient hospice care. Aims: To define the unique pain characteristics of patients admitted to an acute inpatient hospice setting with end-stage dementia or chronic obstructive lung disease (or chronic obstructive pulmonary disease) and to compare them to patients with end-stage cancer. Design: Retrospective patient chart review. Demographic, physiological, pain parameters, and medication utilization data were extracted. Associations between pain characteristics, medication utilization, and admission diagnoses were assessed. Analyses included descriptive statistics. Setting/participants: In total, 146 patients admitted to an acute inpatient hospice between 1 April 2011 and 31 March 2012 with an underlying primary diagnosis of chronic obstructive pulmonary disease (n = 51), dementia (n = 48), or cancer (n = 47). Results: Pain was highly prevalent in all diagnostic groups, with cancer patients experiencing more severe pain on admission. Cancer patients received a significantly higher cumulative opioid dose compared with dementia and chronic obstructive pulmonary disease patients. Pain control within 24 h of pain onset was achieved in less than half of all patient groups with chronic obstructive pulmonary disease patients the least likely to achieve pain control. Conclusions: Despite the fact that pain is the most common complaint at the end of life, pain management may be suboptimal for some primary diagnoses. Admission diagnosis is the strongest predictor of pain control. Patient with cancer achieve the best pain control, and chronic obstructive pulmonary disease patients are the least likely to have their pain adequately treated

Predictors of respiratory cancer-related mortality for Jews and Arabs in Israel

Background: Respiratory cancers, including lung, tracheal and bronchus cancers, are a leading cause of cancer-related mortality in Israel; however, incidence can differ among demographic groups. Despite the importance of sociodemographic characteristics and the interactions between them to incidence and mortality, this topic is understudied. This study analyzes sociodemographic disparities by sex and ethnicity among Jews and Arabs to understand cancer outcome differences stratified by SES, marital status, and number of children as potential contextual factors. Methods: This retrospective cohort study analyzed respiratory cancer-related mortality rates among Israelis born between 1940 and 1960 over 21-years. The follow up period was between January 1, 1996 and 12.31.2016. Mortality rates for Jews and Arabs were calculated. Using a Cox Regression, a multivariate model was constructed to determine the association between ethnicity and respiratory cancer mortality. The study population was then divided into four groups, by sex and ethnicity, to determine the association between marital status, number of children, and SES with respiratory cancer mortality for each subgroup. Results: The overall mortality rate was 0.6%. Arabs had higher mortality rates compared to Jews, even after adjusting for demographic factors including age, sex and SES (Adjusted Hazard Ratio (AHR) = 1.442, 99% confidence intervals (CI) = 1.354,1.546). Among men, a higher mortality rate was found among Arabs (AHR = 1.383, 99%CI = 1.295,1.477), while among women, Arabs had lower mortality rates (AHR = 0.469, 99%CI = 0.398,0.552). Significant mortality rate differences were observed by ethnicity and sex for each sociodemographic variable. Conclusions: This study highlights the importance and implications of understanding differences in respiratory cancer mortality between Jews and Arabs, a minority group in Israel, and is relevant for minority groups in general. There is a need to tailor interventions for these groups, based on differing underlying causes and contextual factors for these cancers. Cancer outcomes among these groups should also be studied separately, by sex, to better understand them

Aspirin use is safe in patients undergoing transbronchial lung cryobiopsy

Background: Aspirin has been shown to be safe for patients undergoing certain diagnostic bronchoscopy procedures, such as transbronchial biopsies and endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration. However, there are no studies documenting the safety of aspirin in patients undergoing trans-bronchial lung cryobiopsy (TBLC). Objective: To determine whether aspirin increases the risk of bleeding during or following TBLC. Methods: 172 consecutive patients undergoing TBLC were included in this retrospective cohort study. Data on demographic characteristics, comorbidities etc. were collected. Bleeding severity was defined by the intervention needed to stop the bleeding: mild-cold saline injection, moderate-adrenalin/hexakarpon injection, or severe - Intensive Care Unit admission after bronchoscopy. Results: Fifty-one patients (29.6 %) were under aspirin treatment at the time of TBLC. Overall, there was no significant difference between the aspirin and the control groups regarding the incidence of moderate-severe bleeding (41.2 % vs. 33.1 %, respectively, p.0.31). the Clopidogrel was found as a risk factor for increased bleeding when taken together with aspirin (Odds ratio = 9.8 (1.1–86), p = 0.013). When taken alone, clopidogrel was also found as a risk factor to increased bleeding, yet these results didn't reach significance due to low number of patients (fig. 1, N = 5, Odds ratio = 2.8 (0.46–17.35), p = 0.245). No difference was observed between the groups regarding additional post-procedural complications, including pneumothorax, hospitalizations, and mortality. Conclusion: To the best of our knowledge, this is the first study examining bleeding risk of cryobiopsy under aspirin treatment. Based on our results, it seems safe to perform TBLC under aspirin treatment, except for patients who are concurrently treated with clopidogrel. Further research should be conducted to substantiate this conclusion
