Treatment at Twilight: An Analysis of Therapy Patterns and Outcomes in Adults 80 Years and Older With Advanced or Metastatic NSCLC.

Introduction: The aim of this study is to evaluate treatment patterns, survival outcomes, and factors influencing systemic treatment decisions in adults 80 years and older with NSCLC. Methods: This was a retrospective National Cancer Database study evaluating outcomes in adults aged 80 years and older with advanced NSCLC. Patients were analyzed on the basis of systemic therapy, including none, chemotherapy or immunotherapy (IO) alone, and chemotherapy plus IO (chemotherapy + IO). Median overall survival (OS) was compared using Kaplan-Meier methodology. Hazard ratio with 95% confidence interval (CI) was used to assess differences in outcomes, and OR with 95% CI was used to assess factors contributing to systemic therapy provision. Results: Patients 80 years and older (OR = 1.135 [95% CI: 1.127-1.142], p = 0.000), females (OR = 1.129 [95% CI: 1.085-1.175], p < 0.001), blacks (OR = 1.272 [95% CI: 1.179-1.372], p < 0.001), non-Hispanic whites (OR = 1.210 [95% CI: 1.075-1.362], p = 0.002), and those with increasing Charlson-Deyo Comorbidity Index score (p < 0.001) were less likely to receive systemic therapy. Median OS for no therapy, IO alone, chemotherapy alone, and chemotherapy plus IO was 2.63 (95% CI: 2.57-2.69), 10.68 (95% CI: 9.96-11.39), 12.35 (95% CI: 11.98-12.72), and 14.03 (95% CI: 13.87-14.88) months, respectively. In chemotherapy alone, mean OS was 1.12 months (95% CI: 0.55-1.70) (p < 0.001) longer with multiagent versus single agent. There was no difference between IO plus single agent versus IO plus multiagent chemotherapy (0.67 mo [95% CI -1.18 to 2.54], p = 1.00). Conclusions: Age, comorbidities, patient race, and sex affected systemic therapy provision. Multiagent chemotherapy and chemotherapy plus IO significantly improved survival; with the latter, survival was similar with IO plus single or multiagent chemotherapy.

Free antibiotic and vaccination programmes in community pharmacies of Miami-Dade County, FL, USA.

OBJECTIVES: Some community pharmacies provide prescribed oral antibiotics for free to incentivize customers. This can influence prescribing practices and may increase inappropriate antibiotic use. Thus, pleas to incorporate education and/or vaccinations into these initiatives have been made by the CDC and IDSA. This study aims to investigate the prevalence and characteristics of free antibiotic programmes (FAPs) and free vaccination programmes (FVPs) offered by community pharmacies within a major US county. Additionally, we evaluated the association between FAP location and proximate socioeconomic status. METHODS: A telephone survey was administered to all community pharmacies in operation and located in Miami-Dade County, FL, USA (n=668). Population characteristics at the five-digit ZIP code level were acquired from the 2010 US Census and American Communities Survey. An independent t-test, Kruskal-Wallis and logistic regression were used for statistical analysis. RESULTS: A total of 660 community pharmacies agreed to the telephone survey (response rate=98.8%). FAPs were present in 6.8% of pharmacies (n=45) and none incorporated an educational component targeted at patients or prescribers. Ciprofloxacin and amoxicillin were offered by all FAPs and 84.4% provided up to a 14 day supply (n=38). Thirty-four of 72 ZIP codes had an FAP and those with a programme had larger populations and higher incomes (P≤0.05). Family income≥$75,000 (P=0.0002) was an independent predictor of FAP availability. None of the surveyed pharmacies offered a FVP. CONCLUSIONS: Frequently provided by chain pharmacies and located in areas of higher income, FAPs within Miami-Dade County offer broad-spectrum antibiotics for long durations without additional education to patients or prescribers.

Developing a strategy to reduce the high morbidity of patients with long-term urinary catheters: the BioMed catheter research clinic.

OBJECTIVE: To assess the idea of managing patients having problems with long-term catheterization (LTC, normally used when all other methods of bladder management have failed or are unsuitable) in a dedicated clinic, to present a prospective analysis of consecutive new patients attending between February 2002 and October 2006, and to establish the incidence of bladder stones in patients who have recurrent catheter encrustation and blockage. PATIENTS AND METHODS: Patients treated with LTC are a large heterogeneous group, mainly consisting of elderly people who have chronic disabilities, and catheter-associated complications occur in > 70% of them. In all, 260 consecutive new patients having problems with LTC were assessed; the evaluation consisted of basic demographics, a detailed history, clinical examination, urine analysis and flexible cystoscopy (FC) via the catheterization route. Patients with bladder stones were screened with FC for recurrence of stones at 3, 6 and 12 months after treatment. RESULTS: In all, 117 men and 143 women (mean age 67.7 years, range 23-97) were assessed; 147 (55.5%) had catheter encrustation. FC showed that 66 of the 147 patients (45%) had bladder stones. Forty-eight patients (73%) were successfully treated at the same clinic appointment and their stones were removed with the help of a tip-less stone basket. Eighteen patients (27%) were referred for inpatient treatment of bladder stones under general anaesthesia. Twenty of 66 patients with bladder stones (30%) formed recurrent bladder stones at a mean (range) follow-up of 8.1 (3-18 months). In addition, 36 patients had successful insertion of suprapubic catheter (SPC) under local anaesthetic in the clinic, and 11 were referred for SPC insertion under general anaesthesia. Two patients were diagnosed with bladder transitional cell carcinoma. CONCLUSION: The introduction of a dedicated catheter clinic, equipped with facilities such as FC and a hoist, enables patients to be treated in an environment that meets their needs and potentially reduces the risk of more complex stone removal and catheter problems at a later date. It can also act as a potential source of data for use in research and development. A significant proportion (45%) of patients with catheter encrustation and blockage had formed bladder stones. Our study provides a rationale for FC of all such patients to detect and remove stones.

A clinical assessment of the performance of a sensor to detect crystalline biofilm formation on indwelling bladder catheters.

OBJECTIVES: To test the ability of a sensor developed to signal infection by the organisms that generate the crystalline biofilms that encrust catheters, to give an early warning that encrustation was occurring on patients' catheters, as the care of many patients undergoing long-term bladder catheterization is complicated by the encrustation and blockage of their catheters. PATIENTS AND METHODS: Twenty patients were followed prospectively for the lifetime of one of their catheters. Sensors based on cellulose acetate/bromothymol blue were placed in the urine-collection bags, which were changed as usual at weekly intervals. The bacteriology was assessed and pH determined weekly on urine samples. Photographic records were made of the sensors twice weekly. On removal, each catheter was examined for encrustation and blockage. RESULTS: Proteus mirabilis was not isolated from five patients and in these cases the sensor colour remained golden-yellow to brown. The catheters drained for the scheduled period and showed no signs of encrustation. By contrast, the sensors turned dark blue/black in the urine of all 15 patients infected with P. mirabilis. All these patients' catheters were encrusted and in 12 the catheters blocked. The mean interval between the sensor signalling and the catheter blocking was 12 days. CONCLUSION: The cellulose acetate/bromothymol blue sensors placed in the urine collection bags are capable of signalling infection by P. mirabilis. They also signal the early stages of catheter encrustation and allow catheter replacement in ample time to avoid the clinical crises and emergency referrals caused by catheter blockage.
