Quality of life after total laryngectomy: evaluating the effect of socioeconomic status.

Total laryngectomy is considered the primary treatment modality for advanced laryngeal carcinoma. This study assessed the quality of life in patients after total laryngectomy, and ascertained whether quality of life is affected by socioeconomic status. Forty-seven patients (20 state- and 27 private-sector) who underwent total laryngectomy between 1998 and 2014 responded to the University of Washington Quality of Life Questionnaire, the Voice-Related Quality of Life Questionnaire and the Brief Illness Perception Questionnaire. Significant differences were found in socioeconomic status between state- and private-sector patients (p < 0.001). There was no significant difference in overall quality of life between groups (p = 0.210). State-sector patients scored significantly higher Voice-Related Quality of Life Questionnaire scores (p = 0.043). Perception of illness did not differ significantly between groups. Overall quality of life after total laryngectomy appears to be similar in patients from different socioeconomic backgrounds. However, patients from lower socioeconomic circumstances have better voice-related quality of life. The results illustrate the importance of including socioeconomic status when reporting voice outcomes in total laryngectomy patients.

A cross-sectional descriptive study of breastfeeding behaviour and galactogogue use among private-sector patients in Cape Town, South Africa

Background . Failure to exclusively breastfeed is often caused by a perception of insufficient breastmilk supply. Galactogogues are frequently prescribed in these circumstances, but this is supported by sparse scientific data with safety concerns for both mother and infant. The exact extent of galactogogue use in South Africa (SA) is not well known. Objectives . To assess breastfeeding behaviour, galactogogue use and perceived galactogogue side-effects among patients attending International Board Certified Lactation Consultant (IBCLC) private practices. Methods . We administered a self-developed, expert-reviewed questionnaire in five IBCLC private practices within the Cape Town Metropole, SA. All patients attending the practices during an 8-week period were invited to participate. Results . Data from 104 participants were included in the study. An exclusive breastfeeding rate of slightly more than 50%, associated with greater parity ( p =0.029), was found. Perceived lack of breastmilk predicted galactogogue use ( p =0.013). There was a high prevalence of galactogogue use (54%), with 80% of these participants using non-prescription medication. Sulpiride was the most common prescription medication used. Increased milk production was reported by 41% ( n =23) of galactogogue users, while 30% ( n =17) reported no effect. Most reported side-effects were minor. Conclusions . Prevalence of galactogogue use exceeded other published data. Sulpiride was most frequently prescribed, despite not being recommended during breastfeeding. A large group of participants reported poor efficacy. The effect of vaginal delivery and immediate skin-to-skin contact after delivery on milk production might be smaller than previously reported in mothers who are personally motivated to breastfeed. Healthcare practitioners should acknowledge breastfeeding mothers’ concerns regarding insufficient milk supply and emphasise correct breastfeeding technique

An evaluation of automated chest radiography reading software for tuberculosis screening among public- and private-sector patients.

Computer-aided reading (CAR) of medical images is becoming increasingly common, but few studies exist for CAR in tuberculosis (TB). We designed a prospective study evaluating CAR for chest radiography (CXR) as a triage tool before Xpert MTB/RIF (Xpert).Consecutively enrolled adults in Dhaka, Bangladesh, with TB symptoms received CXR and Xpert. Each image was scored by CAR and graded by a radiologist. We compared CAR with the radiologist for sensitivity and specificity, area under the receiver operating characteristic curve (AUC), and calculated the potential Xpert tests saved.A total of 18 036 individuals were enrolled. TB prevalence by Xpert was 15%. The radiologist graded 49% of CXRs as abnormal, resulting in 91% sensitivity and 58% specificity. At a similar sensitivity, CAR had a lower specificity (41%), saving fewer (36%) Xpert tests. The AUC for CAR was 0.74 (95% CI 0.73–0.75). CAR performance declined with increasing age. The radiologist grading was superior across all sub-analyses.Using CAR can save Xpert tests, but the radiologist's specificity was superior. Differentiated CAR thresholds may be required for different populations. Access to, and costs of, human readers must be considered when deciding to use CAR software. More studies are needed to evaluate CAR using different screening approaches.

Two echinocandin-resistant Candida glabrata FKS mutants from South Africa

Echinocandins are recommended as first-line agents to treat invasive infections caused by Candida glabrata since this organism is inherently less susceptible to azoles. However, resistance to echinocandins has been described in C. glabrata due to amino acid changes in the hotspot regions of the FKS1 and FKS2 genes. In this report, we describe the first two South African C. glabrata isolates with echinocandin resistance mediated by mutations in the FKS2 gene. Both isolates were cultured from urine specimens from private-sector patients.

A Head-to-Head Comparison of the EQ-5D-5L and AQoL-8D Multi-Attribute Utility Instruments in Patients Who Have Previously Undergone Bariatric Surgery.

Psychosocial health status is an important and dynamic outcome for bariatric/metabolic surgery patients, as acknowledged in recent international standardised outcomes reporting guidelines. Multi-attribute utility-instruments (MAUIs) capture and assess an individual's health-related quality-of-life (HRQoL) within a single valuation, their utility. Neither MAUIs nor utilities were discussed in the guidelines. Many MAUIs (e.g. EQ-5D) target physical health. Not so the AQoL-8D. Our objective was to explore agreement between, and suitability of, the EQ-5D-5L and AQoL-8D for assessing health state utility, and to determine whether either MAUI could be preferentially recommended for metabolic/bariatric surgery patients. Utilities for post-surgical private-sector patients (n=33) were assessed using both instruments and summary statistics expressed as mean [standard deviation (SD)] and median [interquartile range (IQR)]. Interchangeability of the MAUIs was assessed with Bland-Altman analysis. Discriminatory attributes were investigated through floor/ceiling effects and dimension-to-dimension comparisons. Spearman's rank measured associations between the instruments' utility values and with the body mass index (BMI). Mean (SD) EQ-5D-5L utility value was 0.84 (0.15) and median 0.84 (IQR 0.75-1.00). Mean (SD) AQoL-8D utility value was 0.76 (0.17) and median 0.81 (IQR 0.63-0.88). Spearman's rank was r=0.68; (p<0.001); however, Bland-Altman analysis revealed fundamental differences. Neither instrument gave rise to floor effects. A ceiling effect was observed with the EQ-5D-5L, with 36% of participants obtaining a utility value of 1.00 (perfect health). These same participants obtained a mean utility of 0.87 on the AQoL-8D, primarily driven by the mental-super-dimension score (0.52). The AQoL-8D preferentially captures psychosocial aspects of metabolic/bariatric surgery patients' HRQoL. We recommend the AQoL-8D as a preferred MAUI for these patients given their complex physical/psychosocial needs.

Time-of-Day Effects on Surgical Outcomes in the Private Sector: A Retrospective Cohort Study

Surgical care is delivered around the clock. Elective cases within the Veterans Affairs health system starting after 4 pm appear to have an elevated risk of morbidity, but not mortality, compared with earlier cases. The relationship between operation start time and patient outcomes is not described in private-sector patients or for emergency cases. We performed a retrospective cohort study of 56,920 general and vascular surgical procedures performed from October 2001 through September 2004, and entered into the National Surgical Quality Improvement Program database. Operation start time was the independent variable of interest. Random effects, hierarchical logistic regression models adjusted for patient, operative, and facility characteristics. Two independent models determined associations between start time and morbidity or mortality. Subset analysis was performed for emergency and nonemergency cases. After adjustment for patient and procedure characteristics, mortality had a moderately strong association with start time, but only for nonemergency cases starting 9:30 pm to 7:30 am (odds ratio = 1.752; p = 0.028; reference 7:30 am to 9:30 am). As for morbidity, after adjustment, operations starting 9:30 am to 1:30 pm and 5:30 pm to 9:30 pm were associated with a weakly elevated risk of morbidity, but those starting 9:30 pm to 7:30 am demonstrated a strong effect on morbidity (odds ratio = 1.32; p < 0.0001). Subgroup analysis showed this effect was largely a result of elevated risk of morbidity in emergency cases from this overnight time period (odds ratio = 1.48; p = 0.001). Surgical start times are associated with risk-adjusted patient outcomes. In terms of facility operations management and resource allocation, consideration should be given to the capacity to accommodate cases with differences in risk during different time periods.

Successful Implementation of the Department of Veterans Affairs’ National Surgical Quality Improvement Program in the Private Sector: The Patient Safety in Surgery Study

The Veterans Affairs' (VA) National Surgical Quality Improvement Program (NSQIP) has been associated with significant reductions in postoperative morbidity and mortality. We sought to determine if NSQIP methods and risk models were applicable to private sector (PS) hospitals and if implementation of the NSQIP in the PS would be associated with reductions in adverse postoperative outcomes. Data from patients (n = 184,843) undergoing major general or vascular surgery between October 1, 2001, and September 30, 2004, in 128 VA hospitals and 14 academic PS hospitals were used to develop prediction models based on VA patients only, PS patients only, and VA plus PS patients using logistic regression modeling, with measures of patient-related risk as the independent variables and 30-day postoperative morbidity or mortality as the dependent variable. Nine of the top 10 predictors of postoperative mortality and 7 of the top 10 for postoperative morbidity were the same in the VA and PS models. The ratios of observed to expected mortality and morbidity in the PS hospitals based on a model using PS data only versus VA + PS data were nearly identical (correlation coefficient = 0.98). Outlier status of PS hospitals was concordant in 26 of 28 comparisons. Implementation of the NSQIP in PS hospitals was associated with statistically significant reductions in overall postoperative morbidity (8.7%, P = 0.002), surgical site infections (9.1%, P = 0.02), and renal complications (23.7%, P = 0.004). The VA NSQIP methods and risk models in general and vascular surgery were fully applicable to PS hospitals. Thirty-day postoperative morbidity in PS hospitals was reduced with the implementation of the NSQIP.

Adrenalectomy in Veterans Affairs and Selected University Medical Centers: Results of the Patient Safety in Surgery Study

Data from the Patient Safety in Surgery Study were used to compare preoperative risk factors, intraoperative variables, and surgical outcomes of adrenalectomy procedures performed in 81 Veterans Affairs (VA) hospitals with those performed in 14 private-sector (PS) hospitals. This study is a retrospective review of prospectively collected data on all patients undergoing adrenalectomy in the VA and PS for fiscal years 2002 through 2004. Bivariate analysis compared VA and PS preoperative risk factors, intraoperative variables, and 30-day morbidity and mortality. Regression risk-adjustment analysis was used to compare 30-day postoperative morbidity in the VA and PS. During the 3 years studied, 178 VA patients and 371 PS patients underwent adrenalectomy procedures with a median per site of 2 (range 1-9) and 21 (range 8-70) procedures per VA and PS hospital, respectively. The VA patients had considerably more comorbidities than PS patients. The unadjusted 30-day morbidity rate was significantly higher in VA (16.29%) than PS (6.74%) hospitals (p = 0.0003); after controlling for the higher rate of comorbidities, the adjusted odds ratio for morbidity in the VA versus the PS hospitals was no longer significant (odds ratio = 1.328; 95% CI, 0.488-3.613). Unadjusted mortality rate was VA 2.81%, PS 0.27%, p = 0.0074. The low event rate overall precluded risk adjustment for mortality. The VA adrenalectomy population has more preoperative risk factors and substantially higher unadjusted 30-day postoperative morbidity and mortality rates than the PS population. After risk adjustment, there is no significant difference in morbidity between the VA and the PS. A larger study population is needed to compare risk-adjusted mortality between the VA and PS.

Pancreatic Resection in Veterans Affairs and Selected University Medical Centers: Results of the Patient Safety in Surgery Study

Pancreatectomy is a high-risk, technically demanding operation associated with substantial perioperative morbidity and mortality. This study aims to describe the 30-day morbidity and mortality for pancreatectomy and to compare outcomes between private-sector and Veterans Affairs hospitals using multiinstitutional data. This is a retrospective review of patients who underwent pancreatic resection for neoplasia at private-sector (PS) and Veterans Affairs (VA) hospitals participating in the National Surgical Quality Improvement Program Patient Safety in Surgery Study in fiscal years 2002 to 2004. The variables reviewed were demographics, preoperative medical conditions, intraoperative variables, and outcomes. Using logistic regression to control for differences in patient comorbidities, 30-day mortality and morbidity rates between PS and VA hospitals were compared. A total of 1,069 patients underwent pancreatectomy for neoplasia at 97 participating hospitals. Six hundred ninety-two patients were treated at PS hospitals and 377 at VA hospitals. The average number of patients treated at each hospital was 11.0, with a range of 1 to 83 during the 3-year study period. There were 842 patients who underwent pancreaticoduodenectomy (CPT 4815x) and 227 who underwent distal/subtotal pancreatectomy (CPT 4814x). Significant differences were observed between PS patients and VA patients with regard to comorbidities and patient demographics. The 30-day unadjusted morbidity rate was 33.8% overall, 42.2% at VA hospitals versus 29.1% at PS hospitals (p < 0.0001). Unadjusted and adjusted odds ratio (OR) for postoperative morbidity comparing VA with PS hospitals was 1.781 (95% CI, 1.369-2.318) and 1.581 (95% CI, 1.064-2.307). The 30-day unadjusted operative mortality rate was 3.8% overall, 6.4% at VA hospitals and 2.5% at PS hospitals (p = 0.0015). Unadjusted and adjusted OR for postoperative mortality was 2.909 (95% CI, 1.525-5.549) and 2.533 (95% CI, 1.020-6.290), respectively. Similar outcomes were observed when looking at pancreaticoduodenectomy (CPT 4815x) when analyzed independent of other types of pancreatic resections. Pancreatectomies are high-risk operations with substantial perioperative morbidity and mortality. Risk-adjusted outcomes for patients treated at PS hospitals were found to be superior to those for patients treated at VA hospitals in the study.

A Biobehavioral Model for Hospital Psychiatry in an Era of Increasing Regulation and Cost Containment

Psychiatric hospitalization is increasingly a target of cost reduction by employers and third-party payers. The authors describe an evaluation of a biobehavioral model for the treatment of a mixed population of public- and private-sector patients in the psychiatric unit of a general hospital under conditions of severe regulation and cost containment. The program combined behavioral-education technology based on principles of social reinforcement with the traditional medical model in which the psychiatrist specified the patient's individual treatment within the general programmatic framework. Patient progress was monitored using standardized clinic rating scales, which showed that between 85 and 96 percent of the patients had improved significantly at discharge after an average stay of 12 days. Based on that and other findings, the authors believe that the new programmatic technology of biobehavioral psychiatry has the flexibility to ameliorate the adverse effects of increasing regulation and cost containment, even under demanding clinical conditions.
