Secondary healthcare costs after mastectomy and immediate breast reconstruction for women with breast cancer in England: population-based cohort study.

BACKGROUND: Immediate breast reconstruction after mastectomy can improve the quality of life for women with breast cancer and rates are increasing. Long-term inpatient costs of care were estimated to understand the impact of different immediate breast reconstruction procedures on healthcare expenditure. METHODS: Hospital Episode Statistics Admitted Patient Care data were used to identify women undergoing unilateral mastectomy and immediate breast reconstruction in English National Health Service hospitals (1 April 2009 to 31 March 2015) and any subsequent procedures performed to revise, replace, or complete the breast reconstruction. Costs were assigned to Hospital Episode Statistics Admitted Patient Care data using the Healthcare Resource Group 2020/21 National Costs Grouper. Generalized linear models were used to estimate mean cumulative costs for five immediate breast reconstruction procedures over 3 and 8 years, adjusting for covariates (age/ethnicity/deprivation). RESULTS: A total of 16 890 women underwent mastectomy and immediate breast reconstruction: implant (5192; 30.7 per cent), expander (2826; 16.7 per cent), autologous latissimus dorsi flap (2372; 14.0 per cent), latissimus dorsi flap with expander/implant (3109; 18.4 per cent), and abdominal free-flap reconstruction (3391; 20.1 per cent). The mean (95 per cent c.i.) cumulative cost was lowest for latissimus dorsi flap with expander/implant reconstruction (€20 103 (€19 582 to €20 625)) over 3 years and highest for abdominal free-flap reconstruction (€27 560 (€27 037 to €28 083)). Over 8 years, expander (€29 140 (€27 659 to €30 621)) and latissimus dorsi flap with expander/implant (€29 312 (€27 622 to €31 003)) reconstructions were the least expensive, while abdominal free-flap reconstruction (€34 536 (€32 958 to €36 113)) remained the most expensive, despite having lower costs for revisions and secondary reconstructions. This was driven primarily by the cost of the index procedure (€5435 (expander reconstruction) to €15 106 (abdominal free-flap reconstruction)). CONCLUSION: Hospital Episode Statistics Admitted Patient Care Healthcare Resource Group data provided a comprehensive longitudinal cost assessment of secondary care. Although abdominal free-flap reconstruction was the most expensive option, higher costs of the index procedure need to be balanced against ongoing long-term costs of revisions/secondary reconstructions, which are higher after implant-based procedures.

Impact of procedure type on revisional surgery and secondary reconstruction after immediate breast reconstruction in a population-based cohort.

BACKGROUND: Women considering immediate breast reconstruction require high-quality information about the likely need for secondary reconstruction and the long-term risk of revisional surgery to make fully informed decisions about different reconstructive options. Such data are currently lacking. This study aimed to explore the impact of reconstruction type on the number of revisions and secondary reconstructions performed 3, 5, and 8 years after immediate breast reconstruction in a large population-based cohort. METHODS: Women undergoing unilateral mastectomy and immediate breast reconstruction for breast cancer or ductal carcinoma in situ in England between 1 April 2009 and 31 March 2015 were identified from National Health Service Hospital Episode Statistics. Numbers of revisions and secondary reconstructions in women undergoing primary definitive immediate breast reconstruction were compared by procedure type at 3, 5, and 8 years after index surgery. RESULTS: Some 16 897 women underwent immediate breast reconstruction with at least 3 years' follow-up. Of these, 14 069 had a definitive reconstruction with an implant only (5193), latissimus dorsi flap with (3110) or without (2373) an implant, or abdominal free flap (3393). Women undergoing implant-only reconstruction were more likely to require revision, with 69.5 per cent (747 of 1075) undergoing at least one revision by 8 years compared with 49.3 per cent (1568 of 3180) in other reconstruction groups. They were also more likely to undergo secondary reconstruction, with the proportion of women having further reconstructive procedures increasing over time: 12.8 per cent (663 of 5193) at 3 years, 14.3 per cent (535 of 3752) at 5 years, and 17.6 per cent (189 of 1075) at 8 years. CONCLUSION: Long-term rates of revisions and secondary reconstructions were considerably higher after primary implant-based reconstruction than autologous procedures. These results should be shared with patients to support informed decision-making.

BACKGROUND: Breast reconstruction is performed to improve well-being for women who need mastectomy (removal of the breast) as part of breast cancer treatment. There are many different types of breast reconstruction operation, and it can be difficult for women to decide which operation, if any, is right for them. Information about the number of extra operations that a woman is likely to need after breast reconstruction surgery is an important factor in helping them make this decision. This study aimed to investigate the number of extra operations that women who had breast reconstruction needed by 3, 5, and 8 years after surgery, and how this differed by the type of breast reconstruction surgery they had. Routinely collected hospital record data were used to identify women having breast reconstruction at the time of mastectomy for breast cancer, and identify any extra operations performed for problems related to the reconstruction in the 8 years after the first operation. The number of extra operations performed after different types of breast reconstructions was compared at 3, 5, and 8 years after the mastectomy. Women who had implant-based reconstruction required more extra operations than those having reconstruction using their own tissue. They were also more likely to have the implant replaced with another type of breast reconstruction than women undergoing tissue-based reconstruction at 3, 5, and 8 years after the first surgery. This information should be discussed with women thinking about breast reconstruction to help them decide what type of operation would be best for them.

Long-term patient-reported outcomes of immediate breast reconstruction after mastectomy for breast cancer: population-based cohort study.

BACKGROUND: Breast reconstruction is offered to improve quality of life for women after mastectomy for breast cancer, but information regarding the long-term patient-reported outcomes of different reconstruction procedures is currently lacking. The Brighter study aimed to evaluate long-term patient-reported outcomes after immediate breast reconstruction (IBR) in a population-based cohort. METHODS: Women who underwent mastectomy with IBR for breast cancer in England between 1 January 2008 and 31 March 2009 were identified from National Health Service Hospital Episode Statistics. Surviving women were invited to complete the BREAST-Q, EQ-5D-5L™, and ICECAP-A at least 12 years after the index procedure. Questionnaires were scored according to developers' instructions and compared by IBR type. RESULTS: Some 1236 women underwent IBR; 343 (27.8 per cent) had 2-stage expander/implant, 630 (51.0 per cent) latissimus dorsi, and 263 (21.3 per cent) abdominal flap reconstructions, with a mean(s.d.) follow-up of 13.3(0.5) years. Women who underwent abdominal flap reconstruction reported higher scores in all BREAST-Q domains than those who had other procedures. These differences remained statistically significant and clinically meaningful after adjusting for age, ethnicity, geographical region, socioeconomic status, smoking, BMI, and complications. The greatest difference was seen in scores for satisfaction with breasts; women who had abdominal flap reconstructions reported scores that were 13.17 (95 per cent c.i. 9.48 to 16.87) points; P < 0.001) higher than those among women who had two-stage expander/implant procedures. Women who underwent latissimus dorsi reconstruction reported significantly more pain/discomfort on the EQ-5D-5L™, but no other differences between procedures were seen. CONCLUSION: Long-term patient-reported outcomes are significantly better following abdominal flap reconstruction than other traditional procedure types. These findings should be shared with women considering IBR to help them make informed decisions about their surgical options.

Emerging inflammatory bowel disease demographics, phenotype, and treatment in South Asia, South-East Asia, and Middle East: Preliminary findings from the Inflammatory Bowel Disease-Emerging Nations' Consortium.

BACKGROUND AND AIM: Inflammatory bowel disease (IBD) is emerging in the newly industrialized countries of South Asia, South-East Asia, and the Middle East, yet epidemiological data are scarce. METHODS: We performed a cross-sectional study of IBD demographics, disease phenotype, and treatment across 38 centers in 15 countries of South Asia, South-East Asia, and Middle East. Intergroup comparisons included gross national income (GNI) per capita. RESULTS: Among 10 400 patients, ulcerative colitis (UC) was twice as common as Crohn's disease (CD), with a male predominance (UC 6678, CD 3495, IBD unclassified 227, and 58% male). Peak age of onset was in the third decade, with a low proportion of elderly-onset IBD (5% age > 60). Familial IBD was rare (5%). The extent of UC was predominantly distal (proctitis/left sided 67%), with most being treated with mesalamine (94%), steroids (54%), or immunomodulators (31%). Ileocolic CD (43%) was the commonest, with low rates of perianal disease (8%) and only 6% smokers. Diagnostic delay for CD was common (median 12 months; interquartile range 5-30). Treatment of CD included mesalamine, steroids, and immunomodulators (61%, 51%, and 56%, respectively), but a fifth received empirical antitubercular therapy. Treatment with biologics was uncommon (4% UC and 13% CD), which increased in countries with higher GNI per capita. Surgery rates were 0.1 (UC) and 2 (CD) per 100 patients per year. CONCLUSIONS: The IBD-ENC cohort provides insight into IBD in South-East Asia and the Middle East, but is not yet population based. UC is twice as common as CD, familial disease is uncommon, and rates of surgery are low. Biologic use correlates with per capita GNI.

Use of prophylactic mesh during initial stoma creation to prevent parastomal herniation: a systematic review and meta-analysis of randomised controlled trials.

AIM: Parastomal hernia (PSH) is a common complication following stoma creation. Previous reviews found mesh reinforcement during initial stoma creation beneficial in reducing PSH incidence. Since then, several multicentre randomised controlled trials (RCTs) produced widely ranging results rendering previous findings debatable. This current review assessed whether combining the latest larger multicentre RCTs would alter the previous findings. METHODS: The Cochrane Library, MEDLINE and Embase were searched from the respective dates of inception until 15 January 2021. RCTs were included if they compared mesh with no mesh during initial stoma creation in adult patients to prevent PSH. Included RCTs were summarised narratively and meta-analysed to estimate the relative risk (RR) of PSH incidence (primary analysis), peristomal complications and PSH repair (secondary analyses). Several subgroup analyses were performed, including mesh type (synthetic/biologic), surgical technique (open/laparoscopic) and mesh position (sublay/intraperitoneal). RESULTS: Thirteen RCTs were included in the primary meta-analysis (1070 patients); PSH incidence was reduced in patients with mesh compared with patients without mesh at maximal follow-up (RR = 0.54; 95% CI 0.39-0.77; I2  = 67%; P < 0.01). The number of PSH repairs was fewer in patients who had mesh (RR = 0.63; 0.35-1.14; I2  = 6%; P = 0.39), with no difference in peristomal complications (RR = 0.96; 0.55-1.70; I2  = 0%; P = 0.71), comparing with no mesh. Subgroup analyses suggested that placing synthetic mesh using an open sublay technique might be more beneficial. CONCLUSIONS: Prophylactic mesh reinforcement during initial stoma creation reduces PSH incidence and potentially its repair, without an increase in peristomal complications. However, substantial heterogeneity among included RCTs limits confidence in the results.

A semi-Markov model comparing the lifetime cost-effectiveness of mesh prophylaxis to prevent parastomal hernia in patients undergoing end colostomy creation for rectal cancer.

AIM: Parastomal hernia (PSH) is a common problem following colostomy. Using prophylactic mesh during end colostomy creation may reduce PSH incidence, but concerns exist regarding the optimal type of mesh, potential long-term complications, and cost-effectiveness of its use. We evaluated the cost-effectiveness of mesh prophylaxis to prevent PSH in patients undergoing end colostomy creation for rectal cancer. METHODS: We developed a decision-analytical model, stratified by rectal cancer stages I-IV, to estimate the lifetime costs, quality-adjusted life-years (QALYs) and net monetary benefits (NMBs) of synthetic, biologic and no mesh from a UK NHS perspective. We pooled the mesh-related relative risks of PSH from 13 randomised controlled trials (RCTs) and superimposed these on the baseline (no mesh) risk from a population-based cohort. Uncertainty was assessed in sensitivity analyses. RESULTS: Synthetic mesh was less costly and more effective than biologic and no mesh to prevent PSH for all rectal cancer stages. At the willingness-to-pay threshold of £20,000/QALY, the incremental NMBs (95% CI) ranged between £1,706 (£1,692 to £1,720) (stage I) and £684 (£678 to £690) (stage IV) for synthetic versus no mesh, and £2,038 (£1,997 to £2,079) (stage I) and £1,671 (£1,653 to £1,689) (stage IV) for synthetic versus biologic mesh. Synthetic mesh was more cost-effective than no mesh unless the relative risk of PSH was ≥0.95 for stages I-III and ≥0.93 for stage IV. [Correction added on 05 October 2021 after first online publication: The estimation of health outcomes (QALYs) for all three interventions evaluated (synthetic mesh; biologic mesh; no mesh) have been corrected in this version.] CONCLUSIONS: Synthetic mesh was the most cost-effective strategy to prevent the formation of PSH in patients after end colostomy for any rectal cancer stage; however, conclusions are dependent on which subset of RCTs are considered to provide the most robust evidence.

Economic evaluation of GPs' direct access to computed tomography for identification of brain tumours.

BACKGROUND: When GPs suspect a brain tumour, a referral for specialist assessment and subsequent brain imaging is generally the first option. NICE has recommended that GPs have rapid direct access to brain imaging for adults with progressive sub-acute loss of central nervous function; however, no studies have evaluated the cost-effectiveness. METHODS: We developed a cost-effectiveness model based on data from one region of the UK with direct access computed tomography (DACT), routine data from GP records and the literature, to explore whether unrestricted DACT for patients with suspected brain tumour might be more cost-effective than criteria-based DACT or no DACT. RESULTS: Although criteria-based DACT allows some patients without brain tumour to avoid imaging, our model suggests this may increase costs of diagnosis due to non-specific risk criteria and high costs of diagnosing or 'ruling out' brain tumours by other pathways. For patients diagnosed with tumours, differences in outcomes between the three diagnostic strategies are small. CONCLUSIONS: Unrestricted DACT may reduce diagnostic costs; however, the evidence is not strong and further controlled studies are required. Criteria-based access to CT for GPs might reduce demand for DACT, but imperfect sensitivity and specificity of current risk stratification mean that it will not necessarily be cost-effective.

Disconnect between psychiatric and addiction services: a review of patients' attendances at Alcohol Tobacco and Other Drug Services after a psychiatric admission.

OBJECTIVE: To investigate the rate of attendance at Alcohol Tobacco and Other Drug Services (ATODS) for patients discharged from an acute mental health unit with a primary/secondary diagnosis of substance use disorder (SUD); and describe factors, demographics, diagnoses and service provision that relate to their attendance. METHOD: All inpatients between 1 November 2016 and 31 October 2017 with a diagnosis of SUD were compared for their attendance at ATODS within 30 days of discharge. Other measures included their admission data (e.g. demographics, diagnosis), and indices of their illness severity. RESULTS: Of 1295 admissions for a total of 900 patients, 32.4% of patients had an SUD diagnosis. Only 10.3% of these patients attended ATODS. There were no significant differences by gender, age, indigenous status, illness severity or dual diagnosis intervention during their inpatient stay on attendance. Relative to the SUD-only group, individuals with any psychiatric comorbidity were three-four times less likely to attend ATODS. CONCLUSION: Despite the ongoing emphasis on dual diagnosis treatment, the rate of engagement with ATODS remains low. Further review is needed to determine whether enhanced information sharing or case management models may improve attendance rates.

Cadaveric Analysis of Exposure of the Talar Articular Surface Through the Posteromedial Approach.

The purpose of this cadaveric study is to assess the talar articular surface visible through a modified posterior medial approach to the ankle joint for talar osteochondral defects. Ten fresh frozen cadaveric specimens were included. The talar surface area was outlined utilizing a marker. The talus was removed to measure the medial to lateral length and posterior to anterior length using a flexible ruler. A skin incision was made posterior to the medial malleolus. The incision was deepened through the flexor retinaculum. Dissection was carried between the posterior tibial and flexor digitorum longus tendons through the posterior tibial tendon sheath in order to access the posteromedial ankle joint. The posterior tibiofibular ligament should remain intact. A Hintermann distractor was then inserted to distract the ankle joint. The average articular cartilage visible from medial to lateral was 1.90 (68.6%) centimeters, while from posterior to anterior was 2.00 (43.6%) centimeters. Medial malleolar osteotomy is often required to visualize posteromedial talar osteochondral defects that are difficult to visualize with standard anterior ankle arthroscopy. Our study suggests that the modified posteromedial approach between the posterior tibial and flexor digitorum longus tendons and utilizing a Hintermann distractor allows for visualization of common posterior and central-medial lesions. When considering the anatomic 9-zone grid scheme proposed by Raikin et al, zone 4, 7, and 8 lesions can be assessed with this approach. A clinical study should be undertaken to evaluate the morbidity of this approach.

Identification of pathogenic gene mutations in LMNA and MYBPC3 that alter RNA splicing.

Genetic variants that cause haploinsufficiency account for many autosomal dominant (AD) disorders. Gene-based diagnosis classifies variants that alter canonical splice signals as pathogenic, but due to imperfect understanding of RNA splice signals other variants that may create or eliminate splice sites are often clinically classified as variants of unknown significance (VUS). To improve recognition of pathogenic splice-altering variants in AD disorders, we used computational tools to prioritize VUS and developed a cell-based minigene splicing assay to confirm aberrant splicing. Using this two-step procedure we evaluated all rare variants in two AD cardiomyopathy genes, lamin A/C (LMNA) and myosin binding protein C (MYBPC3). We demonstrate that 13 LMNA and 35 MYBPC3 variants identified in cardiomyopathy patients alter RNA splicing, representing a 50% increase in the numbers of established damaging splice variants in these genes. Over half of these variants are annotated as VUS by clinical diagnostic laboratories. Familial analyses of one variant, a synonymous LMNA VUS, demonstrated segregation with cardiomyopathy affection status and altered cardiac LMNA splicing. Application of this strategy should improve diagnostic accuracy and variant classification in other haploinsufficient AD disorders.

Cost-effectiveness of prostate cancer screening: a systematic review of decision-analytical models.

BACKGROUND: There is ongoing debate about the harms and benefits of a national prostate cancer screening programme. Several model-based cost-effectiveness analyses have been developed to determine whether the benefits of prostate cancer screening outweigh the costs and harms caused by over-detection and over-treatment, and the different approaches may impact results. METHODS: To identify models of prostate cancer used to assess the cost-effectiveness of prostate cancer screening strategies, a systematic review of articles published since 2006 was conducted using the NHS Economic Evaluation Database, Medline, EMBASE and HTA databases. The NICE website, UK National Screening website, reference lists from relevant studies were also searched and experts contacted. Key model features, inputs, and cost-effectiveness recommendations were extracted. RESULTS: Ten studies were included. Four of the studies identified some screening strategies to be potentially cost-effective at a PSA threshold of 3.0 ng/ml, including single screen at 55 years, annual or two yearly screens starting at 55 years old, and delayed radical treatment. Prostate cancer screening was modelled using both individual and cohort level models. Model pathways to reflect cancer progression varied widely, Gleason grade was not always considered and clinical verification was rarely outlined. Where quality of life was considered, the methods used did not follow recommended practice and key issues of overdiagnosis and overtreatment were not addressed by all studies. CONCLUSION: The cost-effectiveness of prostate cancer screening is unclear. There was no consensus on the optimal model type or approach to model prostate cancer progression. Due to limited data availability, individual patient-level modelling is unlikely to increase the accuracy of cost-effectiveness results compared with cohort-level modelling, but is more suitable when assessing adaptive screening strategies. Modelling prostate cancer is challenging and the justification for the data used and the approach to modelling natural disease progression was lacking. Country-specific data are required and recommended methods used to incorporate quality of life. Influence of data inputs on cost-effectiveness results need to be comprehensively assessed and the model structure and assumptions verified by clinical experts.

Frequency and determinants of malnutrition in children aged between 6 to 59 months in district Tharparkar, a rural area of Sindh.

OBJECTIVE: To assess the nutritional status of children living in Tharparkar. METHODS: This cross-sectional study was conducted in four villages of Tharparkar district of Sindh, Pakistan, in 2014, and comprised children aged between 6 and 59 months. Data was collected from mothers and anthropometry of children was done using standard techniques. Nutritional status was assessed by using age- and sex-specific World Health Organisation standard charts for underweight, stunting and wasting. Data was analysed using SPSS 16. RESULTS: Of the 304 children assessed, 117(38.5%) were stunted, 58(19.1 %) were wasted and 101(33.2 %) were underweight with no gender discrimination. Under-nutrition was particularly observed in the second year of life. Statistically significant factors associated with stunting were illiteracy of mother, family size of >5 members, pregnancy>4 times, child mortality in last 6 months, absence of breastfeeding and no history of child vaccination(p<0.05 each). Logistic regression revealed family size of <5 members, pregnancy ?4 times, breastfeeding and vaccination were protective factors for stunting (p<0.05 each). Mortality of a child in the last 6 months in the family was 3 times more likely to have a stunted child. CONCLUSIONS: Stunting was the most common type of under-nutrition with no sex discrimination.

Mean Platelet Volume, Red Cell Distribution Width to Platelet Count Ratio, Globulin Platelet Index, and 16 Other Indirect Noninvasive Fibrosis Scores: How Much Do Routine Blood Tests Tell About Liver Fibrosis in Chronic Hepatitis C?

BACKGROUND AND AIM: Many indirect noninvasive scores to predict liver fibrosis are calculated from routine blood investigations. Only limited studies have compared their efficacy head to head. We aimed to compare these scores with liver biopsy fibrosis stages in patients with chronic hepatitis C. MATERIALS AND METHODS: From blood investigations of 1602 patients with chronic hepatitis C who underwent a liver biopsy before initiation of antiviral treatment, 19 simple noninvasive scores were calculated. The area under the receiver operating characteristic curves and diagnostic accuracy of each of these scores were calculated (with reference to the Scheuer staging) and compared. RESULTS: The mean age of the patients was 41.8±9.6 years (1365 men). The most common genotype was genotype 4 (65.6%). Significant fibrosis, advanced fibrosis, and cirrhosis were seen in 65.1%, 25.6, and 6.6% of patients, respectively. All the scores except the aspartate transaminase (AST) alanine transaminase ratio, Pohl score, mean platelet volume, fibro-alpha, and red cell distribution width to platelet count ratio index showed high predictive accuracy for the stages of fibrosis. King's score (cutoff, 17.5) showed the highest predictive accuracy for significant and advanced fibrosis. King's score, Göteborg university cirrhosis index, APRI (the AST/platelet count ratio index), and Fibrosis-4 (FIB-4) had the highest predictive accuracy for cirrhosis, with the APRI (cutoff, 2) and FIB-4 (cutoff, 3.25) showing the highest diagnostic accuracy.We derived the study score 8.5 - 0.2(albumin, g/dL) +0.01(AST, IU/L) -0.02(platelet count, 10(9)/L), which at a cutoff of >4.7 had a predictive accuracy of 0.868 (95% confidence interval, 0.833-0.904) for cirrhosis. CONCLUSIONS: King's score for significant and advanced fibrosis and the APRI or FIB-4 score for cirrhosis could be the best simple indirect noninvasive scores.

Partial Brain Tissue Oxygen Levels Predict Arrhythmia and Prognosis in Patients With Brain Injury.

The objective of this study was to examine the clinical determinants of incidence and prognosis of arrhythmias in the setting of acute brain injury. Acute brain injury is known to cause electrocardiographic abnormalities and cardiac arrhythmias. The relation between partial brain tissue oxygen (PBTO) and intracranial pressure (ICP) with arrhythmia incidence and prognosis remains unknown. Consecutive patients with acute brain injury and intracranial bleed admitted to the neurosurgical intensive care unit were enrolled in the study. Baseline characteristics [demographics, medical history, etiology of brain injury, Glasgow Coma Scale (GCS) score, blood pressure, and respiratory rate] were documented. Patient's telemetry recordings were reviewed for daily mean heart rates and arrhythmias. If arrhythmia was noted, PBTO levels at the beginning of arrhythmia, ICP, brain tissue temperature, and outcomes were recorded. A total of 106 subjects (53% men, age 39 ± 18 years, 65 traumatic and 41 nontraumatic brain injuries) were studied. Overall, 62% of subjects developed a total of 241 arrhythmia episodes. Ventricular arrhythmias were associated with significantly higher daily mean heart rates, low PBTO levels, and low GCS scores, whereas atrial arrhythmias were associated with lower daily mean heart rates, normal PBTO levels, and higher GCS and ICP. Three or more episodes of arrhythmia predicted worse outcomes, including mortality (P = 0.001). In patients with acute brain injury, poor PBTO levels are associated with higher incidence of ventricular tachyarrhythmias. In contrast, atrial tachyarrhythmias occur in patients with normal PBTO levels and higher ICP. Incidence of ventricular arrhythmia in those with poor PBTO is associated with increased mortality.

Down the wrong road - a case report of inadvertent nasogastric tube insertion leading to lung laceration and important pearls to avoid complications.

Nasogastric tube (NGT) insertion is a common procedure performed by residents and nursing staff to access the stomach. Although an apparently simple procedure, it is associated with technical difficulties and complications if proper care is not taken during insertion. We present a case of a 79-year-old female with multiple comorbidities who had a percutaneous enteral gastrostomy tube removed due to infection of an insertion site wound and a NGT was inserted for feeding. A few minutes post-insertion the patient developed shortness of breath and a drop in oxygen saturation. An immediate chest X-ray showed the NG tube traversing along the course of the trachea and the right main bronchus into the right upper abdomen with right-sided pneumothorax. The NG tube was immediately removed and a right chest drain inserted. Subsequent imaging showed right-sided pneumothorax with evidence of lung laceration and underlying lung collapse and diaphragmatic injury. The patient underwent a prolonged course of hospitalisation due to hospital-acquired pneumonia before being discharged upon clinical improvement. We highlight the fact that a simple and routine procedure such as NGT insertion can have devastating complications if due care is not taken. Along with a literature review, we provide and compare different methods to confirm correct placement of a NGT. The article also discusses important pearls for practising physicians and nursing staff to avoid such complications. Owing to the frequency of the procedure in hospitals and long-term care units, appropriate awareness among medical staff is necessary.

The prevention of contrast-induced nephropathy.

OBJECTIVE: Contrast-induced nephropathy (CIN) is a complication which may develop after exposure to iodinated contrast media. The resulting acute kidney injury (AKI) is associated with an increase in both short- and long-term morbidity and mortality, increased hospital length of stay, and greater health care costs. The pathophysiological mechanism associated with the development of CIN remains unknown. This narrative review summarizes the pathophysiology, risk factors, and current evidence for the prevention of CIN. DATA SOURCES: A MEDLINE literature search (2004-May 2014) was performed using search terms contrast-induced nephropathy and prevention. Additional references were identified from literature citations, review articles, and meta-analyses. STUDY SELECTION AND DATA EXTRACTION: Abstracts of English-language human clinical trials that examined therapies for the prevention of CIN were evaluated. Studies that did not investigate a preventative intervention for CIN were excluded. Emphasis was placed on recent publications. DATA SYNTHESIS: A multitude of therapies focused on the prevention of CIN have been investigated. Unfortunately, many of these studies have produced negative and/or inconsistent results. There is a paucity of adequately designed clinical studies evaluating strategies for the prevention of CIN. However, the best data supports use of preprocedural hydration with isotonic solution as the standard of care for prophylaxis. CONCLUSION: Given the poor prognosis associated with CIN, there is need for improved methods to prevent it. At present, the best tools to protect patients from unnecessary risk for CIN are careful assessment of renal function, judicious use of procedures that utilize contrast media, and adequate hydration with isotonic solution.

Economic evaluation of surgical insertion of ventilation tubes for the management of persistent bilateral otitis media with effusion in children.

BACKGROUND: The surgical insertion of Ventilation Tubes (VTs) for the management of persistent bilateral Otitis Media with Effusion (OME) in children remains a contentious issue due to the varying opinions regarding the risks and benefits of this procedure. The aim of this study was to evaluate the economic impact of VTs insertion for the management of persistent bilateral OME in children, providing an additional perspective on the management of one of the commonest medical conditions of childhood. METHODS: A decision-tree model was constructed to assess the cost-effectiveness of VTs strategy compared with the Hearing Aids (HAs) alone and HAs plus VTs strategies. The model used data from published sources, and assumed a 2-year time horizon and UK NHS perspective for costs. Outcomes were computed as Quality-Adjusted Life-Years (QALYs) by attaching a utility value to the total potential gains in Hearing Level in decibels (dBHL) over 12 and 24 months. Modelling uncertainty in the specification of decision-tree probabilities and QALYs was performed through Monte Carlo simulation. Expected Value of Perfect Information (EVPI) and partial EVPI (EVPPI) analyses were conducted to estimate the potential value of future research and uncertainty associated with the key parameters. RESULTS: The VTs strategy was more effective and less costly when compared with the HAs plus VTs strategy, while the incremental cost-effectiveness ratio for the VTs strategy compared with the HAs strategy was £ 5,086 per QALY gained. At the willingness-to-pay threshold of £ 20,000 per QALY, the probability that the VTs strategy is likely to be more cost-effective was 0.58. The EVPI value at population level of around £ 9.5 million at the willingness-to-pay threshold of £ 20,000 indicated that future research in this area is potentially worthwhile, while the EVPPI analysis indicated considerable uncertainty surrounding the parameters used for computing the QALYs for which more precise estimates would be most valuable. CONCLUSIONS: The VTs strategy is a cost-effective option when compared with the HAs alone and HAs plus VTs strategies, but the need for additional information from future study is evident to inform this surgical treatment choice. Future studies of surgical and non-surgical treatment of OME in childhood should evaluate the economic impact of pertinent interventions to provide greater context.

Use of value of information in UK health technology assessments.

OBJECTIVES: The aim of this study was to identify and critically appraise the use of Value of Information (VOI) analyses undertaken as part of health technology assessment (HTA) reports in England and Wales. METHODS: A systematic review of National Institute for Health Research (NIHR) funded HTA reports published between 2004 and 2013 identified the use of VOI methods and key analytical details in terms of: (i) types of VOI methodology used; (ii) parameters and key assumptions; and (iii) conclusions drawn in terms of the need for further research. RESULTS: A total of 512 HTA reports were published during the relevant timeframe. Of these, 203 reported systematic review and economic modeling studies and 25 of these had used VOI method(s). Over half of the twenty-five studies (n = 13) conducted both EVPI (Expected Value of Perfect Information) and EVPPI (Expected Value of Partial Perfect Information) analyses. Eight studies conducted EVPI analysis, three studies conducted EVPI, EVPPI, and EVSI (Expected Value of Sampling Information) analyses and one study conducted EVSI analysis only. The level of detail reporting the methods used to conduct the VOI analyses varied. CONCLUSIONS: This review has shown that the frequency of the use of VOI methods is increasing at a slower pace compared with the published volume of HTA reports. This review also suggests that analysts reporting VOI method(s) in HTA reports should aim to describe the method(s) in sufficient detail to enable and encourage decision-makers guiding research prioritization decisions to use the potentially valuable outputs from quantitative VOI analyses.

Cost-Effectiveness of Routine Monitoring of Long-Term Conditions in Primary Care: Informing Decision Modelling with a Systematic Review in Hypertension, Type 2 Diabetes and Chronic Kidney Disease.

BACKGROUND: Long-term conditions (LTCs) are major public health problems with a considerable health-related and economic burden. Modelling is key in assessing costs and benefits of different disease management strategies, including routine monitoring, in the conditions of hypertension, type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) in primary care. OBJECTIVE: This review aimed to identify published model-based cost-effectiveness studies of routine laboratory testing strategies in these LTCs to inform a model evaluating the cost effectiveness of testing strategies in the UK. METHODS: We searched the Medline and Embase databases from inception to July 2023; the National Institute for Health and Care Institute (NICE) website was also searched. Studies were included if they were model-based economic evaluations, evaluated testing strategies, assessed regular testing, and considered adults aged >16 years. Studies identified were summarised by testing strategies, model type, structure, inputs, assessment of uncertainty, and conclusions drawn. RESULTS: Five studies were included in the review, i.e. Markov (n = 3) and microsimulation (n = 2) models. Models were applied within T2DM (n = 2), hypertension (n = 1), T2DM/hypertension (n = 1) and CKD (n = 1). Comorbidity between all three LTCs was modelled to varying extents. All studies used a lifetime horizon, except for a 10-year horizon T2DM model, and all used quality-adjusted life-years as the effectiveness outcome, except a TD2M model that used glycaemic control. No studies explicitly provided a rationale for their selected modelling approach. UK models were available for diabetes and CKD, but these compared only a limited set of routine monitoring tests and frequencies. CONCLUSIONS: There were few studies comparing routine testing strategies in the UK, indicating a need to develop a novel model in all three LTCs. Justification for the modelling technique of the identified studies was lacking. Markov and microsimulation models, with and without comorbidities, were used; however, the findings of this review can provide data sources and inform modelling approaches for evaluating the cost effectiveness of testing strategies in all three LTCs.

Mortality and neurodevelopmental outcomes of acute bacterial meningitis in children aged <5 years in Pakistan.

OBJECTIVE: Significant neurodevelopmental sequelae are known to occur after acute bacterial meningitis (ABM). This study determined the burden of such sequelae in Pakistani children aged <5 years to guide policies for Haemophilus influenzae type b (Hib) and pneumococcal vaccination. STUDY DESIGN: Cases of ABM were recruited from hospital-based surveillance and assigned to 1 of 3 etiologic groups (Hib, Streptococcus pneumoniae, or unknown etiology). Two age-matched controls were recruited for each case. Six months after enrollment, each case underwent neurologic history and examination, neurodevelopmental evaluation, and neurophysiological hearing test. Controls were assessed in parallel. RESULTS: Of 188 cases, 64 (34%) died. Mortality among subgroups were 7 (27%), 14 (28%), and 43 (39%) for Hib, Streptococcus pneumoniae, and unknown etiology, respectively. Eighty cases and 160 controls completed the assessments. Sequelae among cases included developmental delay (37%), motor deficit (31%), hearing impairment (18.5%), epilepsy (14%), and vision impairment (14%). Sequelae were higher after pneumococcal meningitis (19, 73%) compared with Hib meningitis (8, 53%). Compared with controls, cases were at significantly higher risk for all sequelae (P < .0001). CONCLUSIONS: ABM causes a substantial long-term burden of poor neurodevelopmental outcomes. Hib and pneumococcal vaccines are very effective interventions to prevent meningitis and its disabling sequelae.
