Opioid use disorders and hospital palliative care among patients with gastrointestinal cancers: Ten-year trend and associated factors in the U.S. from 2005 to 2014

Malaria trends in districts that were targeted and not-targeted for seasonal malaria chemoprevention in children under 5 years of age in Guinea, 2014-2021

BACKGROUND

Seasonal malaria chemoprevention (SMC) is a main intervention to prevent and reduce childhood malaria. Since 2015, Guinea has implemented SMC targeting children aged 3-59 months (CU5) in districts with high and seasonal malaria transmission.

OBJECTIVE

We assessed the programmatic impact of SMC in Guinea's context of scaled up malaria intervention programming by comparing malaria-related outcomes in 14 districts that had or had not been targeted for SMC.

METHODS

Using routine health management information system data, we compared the district-level monthly test positivity rate (TPR) and monthly uncomplicated and severe malaria incidence for the whole population and disaggregated age groups (<5 years and ≥5 years of age). Changes in malaria indicators through time were analysed by calculating the district-level compound annual growth rate (CAGR) from 2014 to 2021; we used statistical analyses to describe trends in tested clinical cases, TPR, uncomplicated malaria incidence and severe malaria incidence.

RESULTS

The CAGR of TPR of all age groups was statistically lower in SMC (median=-7.8%) compared with non-SMC (median=-3.0%) districts. Similarly, the CAGR in uncomplicated malaria incidence was significantly lower in SMC (median=1.8%) compared with non-SMC (median=11.5%) districts. For both TPR and uncomplicated malaria incidence, the observed difference was also significant when age disaggregated. The CAGR of severe malaria incidence showed that all age groups experienced a decline in severe malaria in both SMC and non-SMC districts. However, this decline was significantly higher in SMC (median=-22.3%) than in non-SMC (median=-5.1%) districts for the entire population, as well as both CU5 and people over 5 years of age.

CONCLUSION

Even in an operational programming context, adding SMC to the malaria intervention package yields a positive epidemiological impact and results in a greater reduction in TPR, as well as the incidence of uncomplicated and severe malaria in CU5.

Healthcare Utilization Disparities Among Lung Cancer Patients in US Hospitals During 2010–2014: Evidence from the US Hispanic Population’s Hospital Charges and Length of Stay

Purpose

There is a lack of research focused on understanding the differences in the healthcare utilization of lung cancer patients between ethnic groups. This study aims to characterize disparities in healthcare utilization for Hispanic lung cancer patients compared to non-Hispanic patients.

Methods

National Inpatient Sample was used to identify nationwide lung cancer patients (n=141,675, weighted n=702,878) from 2010 to 2014. We examined the characteristics of the study sample by race (Hispanic vs non-Hispanic) and its association with healthcare utilization, measured by discounted hospital charges and length of stay. Multivariate survey regression models were used to identify predictors by racial groups.

Results

Among 702,878 lung cancer patients, 5.1% were Hispanic. Descriptive statistics showed that Hispanics have higher hospital charges and length of stay. Survey regression results also suggested that Hispanic lung cancer patients were associated with higher hospital charges (26.6%) and length of stay (3.5%) than non-Hispanic lung cancer patients. Subgroup analysis displayed a similar trend to the full model.

Conclusion

Healthcare utilization disparities may exist for lung cancer Hispanic patients due to insurance status and early detection. Thus, our findings support providing financial assistance and targeted programs for minority patients. Future health policy consideration should be given to those vulnerable populations where limited healthcare resources are available.

Trends of Opioid Use Disorder and Associated Factors in Hospitalized Patients With Arthritis

Introduction Opioid use was primarily limited to acute pain, postsurgical care, and end of life care setting but now is the most prescribed medication for chronic pain. Arthritis is a chronic disease associated with chronic pain. Given limited options for pain relief in the patient population, these patients are often prescribed opioids and are at increased risk of opioid use disorder (OUD). Therefore, our study aimed to identify factors associated with OUD in patients with arthritis. Methods We analyzed hospitalized adult patients with arthritis with and without OUD using discharge data from National Inpatient Sample (NIS) over five years from January 1, 2010, to December 31, 2014. We looked at trends of OUD in hospitalized patients with arthritis and compared demographic and clinical characteristics of patients with and without OUD using Student's t-test and chi-square test. Multivariate analysis was also used to adjust for variables. Results A total of 21,396,252 arthritis hospitalizations were identified during the five-year study period among which 227,608 had OUD. The prevalence of OUD in arthritis hospitalization increased over the five-year period by 43%. After adjusting for other variables, mental health (OR 2.50 (2.43-2.58)), and substance use (OR 6.39 (6.14-6.66)) disorders were associated with increased odds of OUD. Conclusion The prevalence of OUD among patients with arthritis increased over the five-year study period. Mental health and substance use disorders were associated with increased odds of OUD. More studies are needed to explore alternative pain management options for arthritis patients particularly in those with mental health and substance use disorders.
