Clinical outcomes and cost of open, laparoscopic, and percutaneous ablation for hepatocellular carcinoma

BACKGROUND

Open (OA), laparoscopic (LA), and percutaneous (PA) ablation are all ablation approaches for hepatocellular carcinoma (HCC) utilized in the United States today. However, it remains unclear today which approach is (A) most effective, (B) cost-efficient, and (C) nationally practiced.

METHODS

In-hospital mortality and cost were collected from the National Inpatient Sample (NIS) database for patients undergoing liver ablation from 2011 to 2018. Secondary outcomes included length of stay, disposition, and perioperative composite complications. We used inverse probability of treatment weighting (IPTW) to adjust for differences in patient and hospital baseline characteristics.

RESULTS

One thousand and one hundred and twenty-five LA, 1221 OA, and 1068 PA liver ablations were analyzed. After IPTW, in-hospital mortality risk was significantly lower in PA versus OA cohorts (0.57% vs. 2.90%, p < 0.001) and reduced among PA patients, yet not significantly different from the LA cohort (0.57% vs. 1.64%, p = 0.056). The median length of hospital stay was significantly lower in the PA and LA group compared to OA (2 days vs. 6 days, p < 0.001). The median hospitalization costs were significantly lower for PA ($44,884 vs. $90,187, p < 0.001) and LA ($61,445 vs. $90,187, p < 0.001) compared to OA. Moreover, we found significant regional differences regarding the use of each ablation approach, with the Midwest having the lowest rates of PA and LA.

CONCLUSIONS

Among patients hospitalized after ablation for HCC, PA leads to the lowest hospital cost. Both PA and LA result in lower peri-operative morbidity and mortality relative to OA. Despite these reported advantages, there are significant regional differences with respect to ablation availability suggesting the need to promote the standardization of best practices.

Racial and Socioeconomic Disparities in the Utilization of TKA Among Patients with Posttraumatic Knee Osteoarthritis

Advanced posttraumatic osteoarthritis (PTOA) of the knee is a cause of substantial disability, particularly in younger individuals, and the treatment of choice is total knee arthroplasty (TKA). Racial and socioeconomic disparities exist in the use of TKA, but, to our knowledge, there have been no studies examining these disparities among patients with PTOA.

Obesity Trends Amongst Hospitalized Patients with Spinal Cord Stimulator Implants

INTRODUCTION

Chronic pain remains an important public health problem as it continues to increase healthcare-related cost. Comorbidities like obesity have been associated with efficacy of spinal cord stimulator (SCS) therapy and worse outcomes. The goal of this study is to investigate the trends of obesity amongst hospitalized patients with SCS therapy as well as healthcare utilization outcomes.

METHODS

Using the International Classification of Diseases (ICD) ninth and tenth procedure and diagnosis code, we investigated the National Inpatient Sample (NIS) for patients with SCS implants between 2011 and 2015. Patients received a diagnosis of obesity based on the following categories: class I, II and III obesity. Age, gender, and comorbid conditions of patients with obesity were matched 1:1 on propensity score to those without obesity diagnosis. Our primary outcome was defined as trend of obesity diagnosis. Our secondary outcome, healthcare utilization, included in-hospital cost, length of stay, and discharge location.

RESULTS

Between 2011 and 2015, a total of 3893 patients with SCS implants were identified (average age 56 ± 15 years, 58% female, 0.70 ± 1.1 Charlson Comorbidity Index, CCI). Of this cohort, 640 patients were identified as obese. The proportion of patients with obesity diagnosis increased significantly from 13.75% in 2011 to 19.36% in 2015 (p < 0.001). After 1:1 matching on propensity score, 597 patients with obesity were successfully matched to 597 patients without obesity. The total hospital cost for SCS patients with obesity (median $104,845, IQR $74,648-144,292) was not significantly different from patients without obesity diagnosis (median $111,092, IQR $68,990-145,459) (p = 0.161).

CONCLUSIONS

The data from our study suggests that there is an increasing rate of obesity diagnosis amongst patients with SCS therapy. However, there was no difference in healthcare utilization between patients with and without obesity. Additional studies may provide more insight into our findings.

Socioeconomic Disparities in the Utilization of Spinal Cord Stimulation Therapy in Patients with Chronic Pain

OBJECTIVES

Spinal cord stimulation (SCS) therapies are used in the management of patients with complex regional pain syndrome I (CRPS I) and failed back surgery syndrome (FBSS). The purpose of this study was to investigate the racial and health insurance inequalities with SCS therapy in patients with chronic pain who had CRPS I and FBSS.

METHODS

Patients with chronic pain who had a discharge diagnosis of FBSS and CRPS I were identified using the National Inpatient Sample database. Our primary outcome was defined as the history of SCS utilization by race/ethnicity, income quartile, and insurance status. Multivariable logistic regression was used to determine the variables associated with utilization of SCS therapy.

RESULTS

Between 2011 and 2015, 40,858 patients who were hospitalized with a primary diagnosis of FBSS and/or CRPS I were identified. Of these patients, 1,082 (2.7%) had a history of SCS therapy. Multivariable regression analysis revealed that compared to White patients, Black and Hispanic patients had higher odds of having SCS therapy (Black patients: odds ratio [OR] = 1.41; 95% confidence interval [CI], 1.12 to 1.77; P = 0.003; Hispanic patients: OR = 1.41; 95% CI, 1.10 to 1.81; P = 0.007). Patients with private insurance had significantly higher odds of having SCS therapy compared with those with Medicare (OR = 1.24; 95% CI, 1.08 to 1.43; P = 0.003). Compared to patients with Medicare, Medicaid patients had lower odds of having SCS therapy (OR = 0.50; 95% CI, 0.36 to 0.70; P < 0.001).

CONCLUSIONS

Our study suggests that socioeconomic disparities may exist in the utilization of SCS among hospitalized patients with CRPS I and FBSS the United States. However, confirming these data from other administrative databases, in the outpatient setting, may shed more insight.

Socioeconomic disparities in the utilization of spine augmentation for patients with osteoporotic fractures: an analysis of National Inpatient Sample from 2011 to 2015

BACKGROUND CONTENT

Vertebral augmentation procedures are used for treatment of osteoporotic compression fractures. Prior studies have reported disparities in the treatment of patients with osteoporotic vertebral fractures, particularly with regards to the use of vertebroplasty and kyphoplasty.

PURPOSE

The purpose of this study is to report updates in racial and health insurance inequalities of spine augmentation procedures in patients with osteoporotic fractures.

METHODS

With the use of the National Inpatient Sample, we identified hospitalized patients with osteoporotic fractures between the period of 2011 and 2015. Patients with spine augmentation, defined by the utilization of vertebroplasty and kyphoplasty, were also identified. Our primary outcome was defined as the utilization of spine augmentation procedures across ethnic (white, hispanic, black, and asian/pacific islander) and insurance (self-pay, private insurance, Medicare, and Medicaid) groups. Variables were identified from the NIS database using International Classification of Diseases, Ninth and Tenth diagnosis codes. Univariate and multivariate regression analysis was used for statistical analysis with p value <.05 considered significant. A subgroup analysis was performed across the utilization of kyphoplasty, vertebroplasty, and Medicare coverage.

RESULTS

We identified a total of 110,028 patients with a primary diagnosis of vertebral fracture between 2011 and 2015 (mean age: 74.4±13.6 years, 68% women). About 16,237 patients (14.8%) underwent any type of spine augmentation with over 75% of the patients receiving kyphoplasty. Multivariate analysis showed that black patients (odds ratio [OR]=0.64, 95% confidence interval [CI]: 0.58-0.70, p<.001), Hispanic patients (OR=0.79, 95% CI: 0.73-0.86, p<.001), and Asian/Pacific Islander (OR=0.79, 95% CI: 0.70-0.89, p<.001) had significantly lower odds for receiving any spine augmentation compared with white patients. Patients with Medicaid (OR=0.59, 95% CI: 0.53-0.66, p<.001), private insurance (OR=0.90, 95% CI: 0.85-0.96, p=.001), and those who self-pay (OR=0.57, 95% CI: 0.47-0.69, p<.001) had significantly lower odds of spine augmentation compared with those with Medicare. Comparative use of kyphoplasty was not significantly different between white and black patients (OR=0.85, 95% CI: 0.70-1.04, p=.12). However, Hispanic patients (OR=0.84, 95% CI: 0.71-0.99, p=.04) and Asian/Pacific Islander patients (OR=0.73, 95% CI: 0.58-0.92, p=.007) had significantly lower use of kyphoplasty compared with white patients. The comparative use of kyphoplasty among patients receiving spine augmentation was not significantly different across each insurances status when compared with patients with Medicare.

CONCLUSIONS

Our study suggests that racial and socioeconomic disparities continue to exist with the utilization of spine augmentation procedures in hospitalized patients with osteoporotic fractures.

World Health Organization life-skills training is efficacious in reducing youth self-report scores in primary school going children in Kenya

AIM

Documented evidence shows that training in life skills for school going children improves their physical and mental health status. Although Kenya has a curriculum and a policy for life-skills training in schools, these have not been implemented because lack of local evidence for efficacy. Therefore, the objective of this study was to determine the efficacy and effectiveness of the life-skill training curriculum for primary schools developed by the Ministry of Education, Kenya.

METHODS

We randomly selected 23 schools from two randomly selected sub-counties representing urban/peri-urban and rural contexts in Kenya. We collected baseline socio-demographic characteristics and administered the locally validated youth self-report (YSR) for 11 to 18 years old at baseline and 9 months post-intervention. We used the Ministry of Education validated curriculum for life-skills training for upper primary school as the intervention immediately after the baseline.

RESULTS

The World Health Organization life-skills training is efficacious in reducing YSR scores in primary school going children in Kenya. We found that socio-demographic characteristics were predictors for mental health and that there were significant positive improvements in internalizing and externalizing YSR symptoms and syndromes in both sites. The improvement was over 40% and therefore unlikely to be attributable to placebo effect or natural recovery without intervention. However, attention problems worsened more so in rural sites and particularly in girls.

CONCLUSIONS

Life-skills training is efficacious in improving mental health in school going children in the Kenyan context. However, it is not effective in attention problems which seem to be cognitive in nature.

Prevalence and associated factors of HIV serostatus disclosure to regular female sex partners among HIV-positive men who have sex with both men and women in China

HIV-positive men who have sex with men and women (MSMW) may transmit HIV to regular female sexual partners (FSPs, including girlfriend and wife) through unprotected sex. FSPs' awareness of the HIV serostatus of the MSMW promotes them to access services. However, the prevalence of HIV disclosure among MSMW was low, and factors associated with this disclosure are largely unknown. This study aimed to examine factors associated with HIV disclosure to regular FSPs among HIV-positive MSMW. We recruited 432 HIV-positive MSMW from three provinces of China and collected information on participants' individual characteristics and interpersonal relationships with their FSPs using individualized structured questionnaire. Univariate and multivariate logistic regression were used for data analysis. The prevalence of HIV disclosure to their most recent FSPs was 49.8%. Facilitators of HIV disclosure included the presence of HIV/AIDS symptoms, perceiving this partner's HIV status as positive, exposure to counseling favoring disclosure, inconsistent condom use, and this partner's acknowledgment of MSM identity. Barriers against HIV disclosure included unknown HIV serostatus of this partner and an instrumental relationship to hide MSM identity. HIV disclosure to regular FSPs was low. Programs should target priority subgroups. Services in counseling favoring disclosure and partner HIV testing should be enhanced.

Effects of exposure to anti-vaping public service announcements among current smokers and dual users of cigarettes and electronic nicotine delivery systems

INTRODUCTION

Anti-vaping public service announcements (PSAs) are intended to discourage vaping or use of electronic nicotine delivery systems (ENDS). However, vaping portrayals in PSAs may have unintended effects if they increase smoking or vaping urges. This study examined benefits and unintended effects of anti-vaping PSAs with vapor portrayals on smoking and vaping-related outcomes.

METHODS

Young adult smokers (N = 171) and dual users (N = 122) aged 21-30 years were randomly assigned to view: 1) anti-vaping PSAs with vapor; 2) anti-vaping PSAs without vapor; 3) physical activity PSAs; or 4) anti-smoking PSAs with smoking cues. Outcomes were changes in vaping and smoking urges before and after viewing PSAs, post-test vaping and smoking intentions in the next hour, and post-test intention to purchase ENDS and traditional cigarettes.

RESULTS

Smokers only: Exposure to anti-vaping PSAs with vapor (vs. physical activity) was associated with lower intention to vape and to purchase ENDS (ps < 0.001) and lower intention to smoke and purchase cigarettes (ps < 0.05). Exposure to anti-vaping PSAs with vapor (vs. PSAs without vapor and vs. anti-smoking PSAs with smoking cues) was associated with lower intention to vape in the next hour (ps < 0.05). Exposure to anti-vaping PSAs without vapor (vs. physical activity) was associated with lower change in vaping urge (p < 0.05) and intention to purchase ENDS (p < 0.001). Dual users: Exposure to anti-vaping PSAs without vapor (vs. anti-smoking PSAs) was associated with lower intention to purchase ENDS (p < 0.05).

CONCLUSION

Viewing anti-vaping PSAs with vapor was not associated with unintended effects and may have benefits on reducing smoking and vaping-related outcomes.
